Customer comments
Why purchase an optimized mirror cell? Optimization minimizes
stresses that distort the mirror surface (glass is actually
fluid and slumps) resulting in a degraded image. Proper mirror
support placement produces an optimal image.
All mirrror cells we supply are calculated for the best support
positions using an optimization program. 6" mirror cells
come dotted at the optimal mirror support pad positions, which
are virtually static across a wide range of focal lengths.
We calculate 8" and larger mirror support pad positions
individually for their diameter,
thickness and focal length, so your particular mirror is optimized.
Our mirror clips are also cut to within 1/8" of you mirror's
front surface so it is contained properly in the cell.
