ACHROMATIC LENSES
|
|
Consists of two optical components cemented together
to form an achromatic double. All our achromatic lenses are optimized to correct for
on-axis spherical and chromatic aberrations.
NOTES:
- If the (diameter>30.85x[radius of
curvature]) then no bevel is required.
- Clear Aperture Specification:
3.00 diameter CA=(diameter) - 0.50mm
3.01-12.50 diameter CA=(diameter) = 1.00mm
12.51-75.00 diameter CA=(diameter) - 1.50m
- Coating: 1/4 Wave MgF2 @ 550nm
