Technical Description

(1) The FWO-2B wheel incorporates 5 SM2-threaded filter holders for direct compatibility with 60mm cage coaxial systems. It accommodates Ø2inch optical elements up to 6.4mm thick. A spring-loaded filter wheel with detent positioning ensures accurate centering of filters to the cage system.

(2) Fixed input and output ports on the main body also use SM2 threads to match CSA2 series Ø2inch lens sleeves. For compatibility with standard optomechanical components, the base includes 4 M4 and 2 M6 threaded holes.

(3) Locking screws on the side of cage-rod through-holes are secured with a 1.3mm hex wrench. (Note: The two bottom cage rods can be installed with mounts, but the two top cage rods are blocked by the filter wheel and cannot be installed.)
