Model selection
Why specify NLB20?
NLB20 is a NLB series Lens Mount model. Key selection data: Clear Aperture A (mm): φ17; Optics Size B (mm): φ20; Optics ThicknessC (mm): 3~8; Optic Center HeightH (mm): 20.
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.
