Anti reflection coated optics reduce __________(a) Optical transmission losses(b) Reflection angle(c) Refraction(d) Intensity of star image |
|
Answer» Correct option is (a) Optical transmission losses For explanation: For anti-reflection coated optics, the optical transmission losses may be 1% or 2% at each air to glass or glass to air optical control surface within the telescope, including windows or sensor covers or surfaces. For uncoated optics, the loss per surface is about 4% to 5%. |
