Model selection
Why specify NLB50.8?
NLB50.8 is a NLB series Lens Mount model. Key selection data: Clear Aperture A (mm): φ46; Optics Size B (mm): φ50.8; Optics ThicknessC (mm): 3~10; Optic Center HeightH (mm): 35.
Applications
Stress-free optic retention
Hold a lens without inducing the birefringence or figure error that clamping pressure causes.
Focus and conjugate setting
Position a lens along the axis to place image and Fourier planes where the design requires.
Centration adjustment
Bring the optical axis of the lens onto the axis of the beam rather than the mechanics.
