A grating with high groove density has a high dispersion. This means that the angular separation of wavelengths from the grating is large. It can be desirable to choose a grating with high groove density for two main reasons:
However, there ...

Ibsen Photonics has added nine new Pulse Compression Gratings to our stock available line-up of 100% fused silica transmission gratings for high-power femtosecond laser pulse compression. These gratings cover a broad range of wavelengths from 675 nm to 1030 nm, grouped in the following grating types:
UV-VIS (<800 nm)
800 nm (700-900 nm)
9XX nm
10XX nm
2000 nm
Just like ...

This note describes how an existing spectrometer wavelength range can be scaled by changing the groove density of the transmission grating, without needing to change other aspects of the design. The starting point is a known spectrometer with a grating with groove density G0, detector width LD, and covering the wavelength range λmax,0 – λmin,0.
The focal length of this spectrometer is given by: ...
Ibsen has introduced a new Phase mask product. We are pleased to present that we have developed a technology that allows for the 0. order suppression of Phase masks optimized for 800 nm TE illumination. With 1000-1100 nm period Phase masks, this has not previously been possible.
The development project included a trial production lot of a sample Phase mask of this type, with the following specs:
Engineering Sample Phase mask specifications:
A limited number of this Phase mask is available for immediate ...

Absorbance spectroscopy is a molecular spectroscopy method that uses the wavelength dependent absorption characteristics of materials to identify and quantify specific substances.
Many molecules absorb ultraviolet or visible light emitted from a broadband light source. The absorbance is related to the concentration of the materials in the sample such that stronger absorbance means higher concentration.
There are many different approaches for measuring absorption spectra. ...

In this post, we are focusing on your Raman system, by looking further into Raman spectroscopy, which is a molecular spectroscopic technique providing information about molecular vibrations that can be used for sample identification and quantitation.
Raman spectroscopy has some very unique advantages and is used in many different fields where a non-destructive, microscopic, chemical analysis and imaging is required. This is especially ideal for the pharmaceutical industry where this technique is used for incoming raw material inspection as well as ...
