Long pass razor edge filter

Manufactured by IDEX Corporation

The Long-pass Razor edge filter is an optical component designed to selectively transmit light at wavelengths above a specific cut-off wavelength, while reflecting or absorbing light at shorter wavelengths. It is commonly used in various scientific and industrial applications that require the separation or isolation of specific wavelength ranges within the light spectrum.

For Raman measurements, the excitation
laser was provided by a single-frequency Nd:YVO₄ laser
(DPSS series by Lasos) emitting at 532 nm. The Raman signal was spectrally
dispersed by a ACTON SP750 monochromator with a focal length of 750
mm and equipped with a 300 grooves/mm grating. The signal was detected
by a back-illuminated N₂-cooled Si-CCD camera (100BRX by
Princeton Instruments). The laser light was filtered out by a very
sharp long-pass Razor edge filter (Semrock). The spectral resolution
was 2.8 cm^–1. A 100× objective with NA = 0.9
was employed to excite and collect the light in a backscattering configuration.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
