Angle of Incidence
|
45 degrees with a shift of 0.35%/degree (40 – 50 degrees) |

Non-collimated Light Performance
|
The dichroic beamsplitter’s edge exhibits a small "blue shift" (shift toward shorter wavelengths). Even for Cone Half Angles as large as 15° at normal incidence, the blue shift is only several nm. |
Reflected Wavefront Error
|
< 6λ P-V RWE @ 632.8 nm |
