Variable Attenuator Wheel
OVERVIEW
Variable attenuator (neutral density filter) wheel by DataRay Inc. 4x4 position wheels, 93 dB optical dynamic range, 350 to 2200 nm.
This is a simple-to-use variable attenuator. It consists of a bank of four filter wheels, each with three different filters ranging from 100% transmission down to 0.003 %. This filter bank offers almost continuous attenuation from 0 to more than 93 dB (Optical Density > 9).
Max. attenuation: 93 dB (OD=9)
Min. attenuation: 0 dB
Max. Power Density: Power: 1W/cm²
Energy: 100mJ/cm²
Transmission of filters: See table
Wavelength range: 350 to 2200 nm *
Clear Aperture: 18mm
Angle: 4°
Mounting: 3 x M6 threaded
C-Mount thread
Applications
