Newport MKS Riser Base, 25 mm, SL Series Optical Mounts RH-25

The RH-25 Riser Base is a 25 mm high riser base for use with the SL Series Optical Mounts. SL Series Mounts are configured with a base plate and riser (if required) for a nominal 50 or 75 mm optical axis height. Riser blocks of 25 mm and 50 mm may be placed in any combination beneath the base plate to achieve any optical axis height >75 which is a multiple of 25 mm. For continuously variable height adjustment we recommend the ECN-80 elevator base.
