Examples of use are for photography, audio-visual projection and reflex binocular mounts, because the reflection comes from the front face there are no 'ghost' double images as would be caused by normal 'looking glass' mirror.

Please note that for most orders, mirrors are made/cut to customers requirements. It should be possible to supply directly from stock, but not in all instances. If you need an item by a specific date, you must make us aware of the situation when ordering.

If there were to be a delay of more than a few days in sending out your order, we would contact you and take payment only when goods were ready to send.

You may have any size to your specification with sizes cut to mm or inches. The standard sizes below are given as a useful guide to mirror cost. These and smaller sizes are also available in thinner glass. Mirrors are normally cut to +/- one mm. These are all manufactured from Pilkington, best quality float glass. Mirrors are normally smoothed with no sharp edges and slightly blunted corners for safety.

Information on FS Mirrors for Binocular Mounts
Practical tests have shown that the standard Pilkington float supplies as good an image when used for this purpose as does the 10 mm 'optical' glass. Binocular Mirror Stand
The standard float can be satisfactorily used for binoculars with magnification up to 12x and lenses up to 60mm diameter. It can also be used for binoculars magnifying up to 20x with lenses up to 80 mm diameter, if carefully selected by optical testing. If you need a piece for a larger binocular please ask for a price.
For binoculars larger than 20 x 80, you would almost certainly need optical flats with an optical accuracy better than 1/2 wave over the whole surface. Unfortunately we cannot help with this but know of customers who have obtained suitable pieces from 'army surplus' supplies.
