Low Voltage DC / Battery Powered HV Amplifiers
WMA-02 And WMA-02LF
-
The Falco Systems WMA-02 is a high voltage amplifier that runs from an 24 - 30V DC power supply and can be battery powered if required, e.g. for use in a Faraday cage. Its internal high voltage generator is inductor-free and hence does not spread magnetic interference in sensitive experimental setups. The output noise is impressively low at 4mVrms. For extremely low noise applications where bandwidth is not an issue, a dedicated WMA-02LF version is available that contains an output low pass filter capacitor which reduces the bandwidth to 50Hz, but makes the noise drop to below 0.2mVrms. This bandwidth-limited amplifier is ideal for MEMS or piezo positioning with manual voltage adjustment.

Monochromator Gratings - Type IV
-
HORIBA Scientific produces a wide range of holographic master gratings from which high precision replicas are manufactured.Using Type IV aberration-corrected monochromator gratings, a single concave grating disperses, collimates, and refocuses the light from the entrance slit onto the exit slit. Wavelength scanning is obtained through a simple rotation of the grating.The groove spacing of these gratings is computer-optimized to produce high quality images with a minimum of astigmatism and coma, even at large numerical apertures. Compared with Czerny-Turner monochromators (equipped with one plane grating, one collimating mirror and one focusing mirror), Type IV aberration-corrected monochromator gratings provide much better light collection efficiency and signal-to-noise ratio.
