Optical Surfaces achieves high stability and performance in its reflective beam collimator kits using a zero-expansion parabolic mirror manufactured to better than lambda/10 peak-to-valley surface accuracy.
Typical beamsplitters from Optical Surfaces Ltd. are manufactured to a surface accuracy of lambda/20 peak-to-valley at 633 nm.
Optical Surfaces Ltd. routinely produces large-diameter reference flats with typical wavefront error of up to lambda/20 p-v.
Optical Surfaces beam collimators use a zero expansion off-axis parabolic mirror manufactured to better than lambda/10 p-v surface accuracy.
The RFBUC4G5GAB BUC from RF-Lambda has an input/output L-band VSWR of 1.5:1, in-band spurious of 55–62 dBc, a P1dB of 33 dBm, and requires a 12 V DC supply with 1.65–2 A current consumption.
Optical Surfaces Ltd. can routinely achieve a surface accuracy better than lambda/20 p.v.
The chosen TDK-Lambda UK Genesys+ half-rack power supplies enabled all 140 required units to fit into the available volume within the chamber.
