Spectral sensor platforms for use with microfluidic chips

Knight Photonics and Camtech Innovations have developed multiple optical sensors integrated with microfluidic chips [lab-on-chip], based on active holograms or fluorescence. These are incorporated into dedicated instruments with spectrometers or non-dispersive optical detectors to interrogate the chips.

These sensors have significant potential to providing economical label- free detection solutions, and are available for portable, laboratory, point of care, industrial and environmental instrumentation. Typical applications are in biodefense, medical diagnostics, water and food testing. However this is backed by world- class facilities for fabrication, prototyping, and manufacturing of lab-on-chip devices and optical instrumentation for many applications.

For those developing their own lab-on-chip platforms we provide an extensive variety of microfluidics chip fabrications with accessories such as syringe pumps, multiple chip holders, XYZ motions, and microscopes with digital imaging to complete a system. For spectroscopy and optical detector sensing interfacing is available with micro optics, fibre optics, optical probes with option to applied multiplexing of the chips.

Rock and Aggregate Analyser

The Petroscope Process Analyser has evolved from the specialist knowledge in Iceland of  rock particle and aggregate selection. Success and optimisation of each engineering and civil construction application requires very careful selection and use of specific rock particle specifications. Applications include underpinning of high speed railways, construction of earthquake resistant buildings, correct construction of weatherproof highways and runways, and much more.

The Petroscope is automated to analyse a conveyor feed of particles for size, and  shape, by laser scanning; and composition by spectroscopy. Petromodel ’s unique neural software uses the sensor primary data to provide a full  profile of each particle for selection.

Spectral Goniometer

Knight Photonics Manufacturing introduces new Goniometers for Spectral angular studies in:-


The goniometers provide independent angles of illumination and light detection in several planes. The swing arms accept fibre optics to allow illumination from lights sources and detection to spectrometers or single detectors. Filters and polarisers can be included. The Optical geometry caters for both collimated or focussed light.

For liquids the inserts can be thermostated. The cradle has calibrated lateral motion, so that it  can also be used for slides and separative chemisty.  A range of goniometers cater for both medium and  high accuracy analyses.


These small spectrometers, operate as compact handheld bench or wall mount, instruments. They are able to analyse samples for fluorescence, absorption, reflection, colour, and Raman, using micro and macro fibre optic probes, or remote optical sample geometries. The instruments can be used to capture target IMAGES and measure SPECTRA simultaneously. The screen size is 10” or 12”, with touch keyboard and optional hard keyboard The software is “APP” based and the unit can be used for standard internet connection and data transfer. The units are battery or mains powered with on board LED, including UV LED option or tungsten xenon ultra- compact source. Other sources which are external include micro lasers from our associate RGB Laser-systems.
