The Andor Shamrock SR-750 is based on Czerny-Turner optical design. The Shamrock is available as a pre-aligned detector/spectrometer option allowing for seamless integration of software,…

The dispersed light is then re-imaged by the spectrograph and the required wavelength range is directed to a detection system. Gratings consist of equally spaced parallel grooves, formed on a reflective coating and deposited on a substrate. The shape of the grooves (blaze angle) influences what wavelength range the grating is best optimised for.

"We are getting great feedback from the field on the camera image quality – people are saying things like spectacular and magnificent. This, of course, starts with the excellent lens you are delivering."

As an automotive-qualified Tier2 supplier our portfolio and expertise include optics for Driving, Parking, and Infotainment camera systems for OEM passenger and commercial vehicles as well as for HD lighting headlamp modules.

We provide high-resolution custom optics suitable for limited-use or disposable medical devices. These lenses are designed with bio-compatible materials and are assembled in a dedicated medical device cleanroom environment.

The dispersion and efficiency of a grating are dependant on the distance between adjacent grooves and the groove angle. Gratings are generally better than prisms - they are more efficient, they provide a linear dispersion of wavelengths and do not suffer from the absorption effects that prisms have which limits their useful wavelength range.

These influence the choice of grating line density, blaze angle/wavelength, master (different masters for a given line density and blaze angle yield different efficiency and polarisation characteristics) and grating size.

From our early days, we provided our customers in the video conferencing and media markets with optics that delivered on the highest image quality, low distortion, and low F/# to enable high frame rates in low light situations.

What isorder of diffractionin Bragg's law

where: n is the order of diffraction, λ is the diffracted wavelength d is the grating constant (the distance between successive grooves) θi is the angle of incidence measured from the normal and θd is the angle of diffraction measured from the normal. The diagram above shows the orders of the diffracted wavelength. As well as positive orders, light can also be diffracted in the opposite direction (i.e. n = -1, -2 etc.) Higher orders may also appear, but these decrease in intensity. Usually the first order lines (n=1 or n=-1) are the most intense.

Expected spectral resolution and simultaneous bandpass are also influenced by how light is coupled into the spectrograph, the central wavelength of interest and associated grating “working angle”, as well as the detector pixel array format at the output plane. Some of these trade-offs can be assessed with the Andor resolution calculator for Kymera and Shamrock Czerny-Turner spectrographs.

A diffraction grating is an optical element, which separates (disperses) polychromatic light into its constituent wavelengths (colors). The polychromatic light incident on the grating is dispersed so that each wavelength is reflected from the grating at a slightly different angle. The dispersion arises from the wavefront division and interference of the incident radiation from the periodic structure of the grating.
