Features

Manual Fixed Wavelength Laser Beam Attenuators

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 control attenuation.

CONEX Motorized Fixed Wavelength Laser Beam Attenuators

The motorized versions of the VA-CB series come with a motorized rotary stage containing the half-waveplate. Software is included which allows the user to calibrate the VA-CB at a single wavelength on either exit port. The motorized version can be used in open- or closed-loop operation.

Motorized, Variable Beam Splitter (Post and post holder sold separately)

Compact Industrial Housing

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 90°. A removable beam dump is included on the reflected beam port, allowing the use of the VA-CB as 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.

Zero-order Half-waveplate & Polarizing Cube Beamsplitter Design

The VA-CB series is based on zero-order half-waveplates and polarizing cube beam splitters. The high pulsed power versions use high energy Nd:YAG polarizing cube beam splitters and are designed to handle high energy pulses up to 2 J/cm2 at fixed wavelengths including 248 nm, 266 nm, 355 nm, 405 nm, 532 nm and 1064 nm. These beam splitters can also be used with CW lasers at these specified wavelengths. All other beam splitters are designed to handle CW or lower 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.
