Product Series Overview
Fixed Wavelength Variable Beam SplittersNewport's VA-CB series of variable beam splitters provide continuous beam splitting or attenuation for CW lasers at specific wavelengths. The VA-CB series is designed to provide high contrast beam splitting of linearly polarized light. The manual versions of the VA-CB series come with a manual rotary stage containing the half-waveplate. The user manually rotates the stage to adjust the beam splitting ratio.
The VA-CB high energy series is based on zero-order half-waveplates and laser line polarizing cube beam splitters. These beam splitters are designed to handle CW or high energy pulsed laser input up to 2 MW/cm2 CW, 1 J/cm2 at fixed wavelengths including 442 nm, 488 nm, 515 nm, 633 nm, 780 nm, 830 nm, 1300 nm and 1550 nm.
The optics and high-precision opto-mechanics are incorporated into a compact housing, flexibly designed for post mounting at varying optical axis heights. P-polarized light is transmitted with minimal loss collinear to the input beam path while S-polarized light is reflected 90º. A removeable beam dump is included on the reflected beam port, transforming the VA-CB into a variable attenuator for the transmitted beam. M-4 and 8-32 mounting threads are included on the opposite side and bottom of the housing. This allows for various polarized output options.
