Variable Neutral Density Filter Rotation Mounts
Variable Neutral Density Filter Rotation Mounts
The document provides specifications for single and dual filter wheel setups, detailing optical density values for primary and secondary wheels. Optical density values are additive, allowing for a wide range of densities by combining filters. Neutral density filters have a diameter of 25–25.4 mm and a maximum thickness of 3 mm.
Ordering Information
Various models of filter mounts and wheels are available, including:
- FWM1X6: Filter Mount with a single wheel for six 1-inch optics.
- FWM1X12: Filter Mount with a dual wheel for twelve 1-inch optics.
- FWM: Filter Mount only, without a filter wheel.
- FW1X6: Filter Wheel only for six 1-inch optics.
Model 946 and 941 Mounts
Model 946 is a precision kinematic mount for circular variable neutral density filters, offering angular adjustment of ±4° about two orthogonal axes. Model 941 provides basic mounting compatibility with posts, platforms, and clamps. Both models allow smooth, stable rotation of circular variable attenuators.
Beam Steerers
The BSD Series Beam Steerers allow precise control of laser beam height and direction. They feature two adjustable mirror mounts for fine angular adjustment with 5 arc sec sensitivity. The beam steerer is compatible with standard 1-inch diameter mirrors and can be securely mounted on an optical table.
Key Features
- Precise beam direction and height control.
- High-stability stainless steel post for secure mounting.
- Compatible with standard optical components.

An integrated pointer on the mount indicates the setting of the graduated scale on the attenuator. Model 941 offers the widest possible aperture and provides basic mounting compatibility with posts, platforms and clamps. The spindle is integrated into a block with an array of tapped and clearance holes. * Circular filters sold separately.
