Beam collimators feature achromatic design
LW-series beam collimators incorporate a low-expansion off-axis parabolic mirror, manufactured to greater than λ/10 p-v surface accuracy. The all-reflecting design is achromatic with aluminum/magnesium fluoride coatings, stress-free mounts, pre-alignment, and 20 mm field of view. Intended for modulation transfer function testing of optical systems, the off-axis design produces no central obscuration.
