Secondary flat mirror 112 wave (DIAGONAL) are optically flat yield optimum performances when combined with above astronomical mirrors. Each mirror is aluminized and over coated.
GSO offer secondary flat telescope mirrors to match the complete telescope set request. Our elliptic flat mirror has the same high optical quality as our parabolic primary mirrors using BK7 quality glass. All of the mirror surface quality over 112 wave RMS at the least, typically better.
All mirrors have an aluminum reflective coating of 93%. The aluminum coating is protected by a quartz overcoated to make the layer durable against aging effects.
