IRIS is the new option for Gamma Scientific’s RS-7 LED Light Sources

Gamma Scientific has just announced the release of their RS‐7 IRIS option that allows easy adjustment of the light source’s output intensity.

This new enhancement for the SpectralLED® family of uniform intensity tunable light sources considerably increases the dynamic range of the light source. It is particularly useful for irradiance testing and characterisation of bare sensors.

The stepper motor controlled iris provides a variable output aperture which is fully integrated into the light source architecture. Available for both the visible and SWIR output models, the standard RS‐7 firmware includes aperture control and additional API commands.

About the SpectralLED®

The RS‐7 base platform incorporates the latest LED technology available. The RS‐7 VIS series contains 35 discrete wavelength LEDs, delivering a nearly continuous spectrum from 380 to 1000 nm. This allows for an unprecedented colour gamut and applications otherwise impossible for traditional halogen or LED light sources.

The SpectralLED® SWIR series employs LEDs at 9 discrete wavelengths from 900 to 1700 nm in the short‐wave infrared portion of the spectrum, providing a fully programmable spectra with highly uniform and stable output.

The standard configuration incorporates a controller and all software for full spectral calibration with spectral fitting, preset storage and real‐time optical feedback in a variety of measurement units.

USB drivers for Windows, OSX and Linux platforms are included, and external interface and control can be easily achieved via simple ASCII commands.  Custom configurations are also available.  For more information, please contact us or visit: https://www.elliotscientific.com/Gamma-Scientific-Light-Sources

 

 


Using the most powerful single-chip LEDs available, Prizmatix LEDs are ideal for microscopy and optogenetics research

Prizmatix LEDs for Optogenetics and Fluorescence
  • High-power collimated and fibre-coupled LEDs
  • Wavelengths available from UV to Red
  • White Light and Multiple LED Sources

Prizmatix specialises in LED illumination systems for industrial applications, and science, especially in microscopy and optogenetics research.

The Prizmatix High Power and Ultra-High-Power (UHP) models are built using the most powerful single-chip LEDs available. These versatile illumination solutions offer:

Modularity
The modular systems deliver flexibility with a collimated beam. Fitted with a standard SM1 thread at the port, they can be fitted with a variety of accessories such as a fibre coupler adaptor, beam combiner, filter wheel, and more. The accessories are easy to fit and swap, so different set-ups only take minutes.

High efficiency
The fibre-coupled LED models have a highly efficient coupling that optimises the output such that these systems deliver roughly 1.5x more light when compared to Prizmatix LEDs used with a fibre adaptor. The LED controller is in-built to maximise its compactness.

Wide range of powers
High Power LED models are equipped with a 1 mm² single chip LED and can deliver up to 300 mW of optical power, while the UHP models have a 12 mm² single chip LED punching out up to 5 W of optical power. (As measured after the collimating optics)

Broad range of wavelengths
Choose from dozens of standard LEDs that operate at monochromatic wavelengths between 340 and 940 nm, and ‘white’ light models with a choice of spectral outputs. Deep UV and IR LEDs are also available on request.

Controls
Each of the extremely low-noise LED controllers has TTL and analogue input. In combination with a USB-control box, the LEDs can be controlled from a PC using µManager, LabView, Matlab or directly using HyperTerminal commands. An optional photodiode feedback loop enables the LEDs to be power stabilised.

Accessories
In addition to fibre coupling adaptors, collimators and filter wheels, custom-made fibres and fibre bundles with high numerical apertures of up to 0.63 are available. Optogenetics researchers can also order cannulae, rotary joints, and programmable signal generators for use in their experiments.

For more information, please visit our Prizmatix webpages or contact us.

Prizmatix impresses at Neuroscience 2018

Prizmatix has been wowing the crowds at Neuroscience 2018 in San Diego this week with their self-contained UHP-M, an ultra-high power UV & Visible light source for many microscopy applications.

Incorporating two independently controllable Prizmatix large-chip LEDs, the UHP-M delivers broadband white light from a single 55 W LED, and high power UV from a single 10 W LED operating at 365, 385 or 405 nm depending on model ordered. The UHP-M offers:

  • Optically isolated TTL & analogue inputs
  • Fast TTL switching
  • Low optical noise
  • Long life (no lamp replacement)
  • Fanless operation
  • Remote control*
  • USB interface*

* The UHP-M requires no external control if operating at full power. However, if power levels need to be adjusted, the optional remote control or USB interface will be required.

Prizmatix also announced the introduction of a digital micromirror device (DMD) module for delivering light to cellular and subcellular targets. Applications include: optogenetics, uncaging, photoactivation and fluorescence recovery after photobleaching (FRAP).

The one megapixel DMD utilises a grid of 914 by 1140 independently controllable micromirrors to divert light to specific areas under study at over 1000 times per second.

This exciting new product offers almost spatial light modulator (SLM) performance without the need to use lasers, and we’ll know more about it soon.

There’s still time to visit Prizmatix in booth 3333 as Neuroscience 2018 continues until November 7th.

New high output tuneable light source… The Hyperchromator

An efficient monochromator utilising the high-brightness Energetiq EQ-99X LDLS Laser Driven Light Source (right) has been developed by Mountain Photonics, and was recently demonstrated on our booth at Photonics West.

The Hyperchromator uses an off-axis parabolic mirror to focus the broadband light generated by the small plasma spot of the LDLS™ directly onto a diffraction grating, and then off a second mirror to an exit port.

As no entrance slit is used, the optical efficiency of the system is very high – typically f/1.5 or f/2, depending on the required resolution or throughput. A white light bypass output is also available.

The output port has been designed to allow for a multitude of illumination or light coupling options. By using standard catalogue components, the Hyperchromator can be easily integrated into an application.

The Hyperchromator is controlled via USB/RS-232 and an intuitive GUI, with LabVIEW™ and other software libraries supported.

Existing owners of an Energetiq EQ-99X LDLS™ can add tuneability by purchasing the Hyperchromator unit alone.

Please contact us for further details, or download the datasheet.


New tuneable NIR LED source from Gamma Scientific

A new near infra-red tuneable light source has been developed by Gamma Scientific from their existing digitally programmable SpectralLED RS-7 LED system.

The RS-7-SWIR incorporates 9 shortwave infrared wavelengths for synthesis of commercially available light sources or a spectra of your own design.

The platform is easily adaptable for automated test systems and production line integration, with integrated optical feedback and temperature control to ensure rock-solid stability and consistent results.

For more information about this or other light sources and instrumentation Gamma Scientific manufacture, please contact us.


New UV laser source for CRAIC Technologies’ 20/30 PV™ Microspectrophotometer

The introduction of new UV laser sources will dramatically enhance the capabilities of the 20/30 PV™ microspectrophotometer from CRAIC Technologies in terms of both fluorescence and photoluminescence microspectroscopy.

The major application will be to serve as an intense excitation source for fluorescence and photoluminescence (PL) microspectroscopy. This will broaden the range of materials that can be caused to emit photons via a luminescent process.

The 20/30 PV™ microspectrophotometer combines the latest technologies to allow the user to see and measure UV-visible-NIR range transmission, absorbance, reflectance, emission and fluorescence spectra of sample areas smaller than a micron across. Thin film thickness and colour spaces can also be determined.

Scientists in the UK and Ireland involved in forensics, geology, gemology, biochemistry and spectroscopy among others, contact us now to discuss specifications and pricing.
