In the collection arm a 690nm long pass filter was used to cut off the laser and lead the luminescence into the spectrometer (Princeton-Instrument SP2750i) which is equipped with a liquid nitrogen cooled charge coupled detector.

This can include light that did not travel through the sample or photons of the wrong wavelength hitting a pixel. Stray light has many sources including ambient light that leaks into the instrument light that bypasses the sample (like light that gets wave-guided through a cuvette wall) higher-order diffraction from the grating and ...

A short-pass filter (SP) was placed in the pump path before the dichroic to prevent the SERS signal being contaminated by long wavelength amplified spontaneous emission from the laser source. A long-pass filter (LP) was placed in the signal path to prevent 785 nm light …

For example if the biological sample to be imaged has an absorption peak at a short wavelength e.g. at 532 nm then the surface-sensitive photonic microscopy operating at this wavelength will be more sensitive to changes in the sample than the microscopies working at other wavelengths. Furthermore light beams at shorter wavelengths are ...

Back to Laser Safety Sub-TOC. Introduction to Laser Safety Lasers are unique in their safety hazards particularly to something you value highly - your vision. While the dangers of firearms and explosives are obvious to most sane people the possibility that a stream of massless photons even from a low power laser can cause instant severe and irreversible damage to vision or even total ...

It's also safe to say that those cheap high-power lasers are built for output power not monochromaticity. If (a big if) it's actually a narrow pass filter then you'd put it right after the laser emitter before the rest of the optical train. It might cut down a …

We report on multilayer high efficiency antireflection coating (ARC) design and development for use at UV wavelengths on CCDs and other Si-based detectors. We have previously demonstrated a set of single-layer coatings which achieve >50% quantum efficiency (QE) in four bands from 130 to 300 nm. We now present multilayer coating designs that significantly outperform our previous work between ...
