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:

1. If the (diameter>30.85x[radius of curvature]) then no bevel is required.

2. 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

3. Coating: 1/4 Wave MgF2 @ 550nm
