Continuously Variable Neutral Density Filter Wheel for 30 mm Coaxial Systems CNDFR-50C-4M

Continuously Variable Neutral Density Filter Wheel for 30 mm Coaxial Systems — Model CNDFR-50C-4M

Continuously Variable Neutral Density Filter Wheel for 30 mm Coaxial Systems

Product Description

• OD value adjustable through rotating the angle
• Ø50 mm filter wheel
• Continuous and stepped options available
• Applicable for 240 - 1200 nm

The LBTEK Neutral Density Filter Wheel for 30 mm coaxial systems features a UV fused silica base with a metal (Inconel) coating. Continuous and steped neutral density filters are available. The continuous neutral density filters have OD ranges of 0.04-2.0, 0.04-4.0, or 0.04-6.0, while the step-index neutral density filters have OD ranges of 0.04 to 1.0 or 0.04 to 3.0. The filters have a diameter of 50 mm and are mounted on a rotating lever arm for easy removal from the optical path. The filter wheel features 30 mm coaxial mounting plates on both sides, which include internally SM1-threaded ports and four through holes for integration into coaxial systems. Additionally, an M4 tapped hole is located on the bottom for mounting to 12.7 mm series posts and accessories.

Continuously Variable Neutral Density Filter Wheel for 30 mm Coaxial Systems

• Substrate Material: UV Fused Silica
• Coating: Inconel
• Rotatable with swivel lever arm
• Compatible with SM1 lens tubes and 30 mm cage systems
• M4 threaded holes on bottom

The LBTEK continuous neutral density filter wheel is designed for 30 mm coaxial systems, with precision engineering to minimize the impact on the optical element's clear aperture. The coated side is marked with a scale, and for optimal performance, it is recommended to have light incident from this side. It is compatible with both SM1 lens tubes and 30 mm coaxial systems. Additionally, the coaxial plate features an M4 threaded hole at the bottom for mounting to our 12.7 mm series posts and accessories.
