OptoSigma offers a broad selection of Lens mounts (Lens Holders). Some holders are fixed and others have adjustments to position the optics. Each holder is equipped with an 8-32 or M4 thread for mounting onto a post, pedestal, or fixed base. Center heights are in multiples of 5mm and appropriate spacers are available to compensate for height differences within the system. For experimental and prototype use, these holders may be mounted onto optical breadboards or rails.
