Other Services

Reflex Camera Mirror Refurbishment
re-coats are £20 plus p&p
re-makes are £30 plus p&p

Prism Refurbishment

Prisms from nautical instruments and microscopes are usually no problem.

However, we are not camera repairers, or experts.

It may or may not be able to re-coat prisms from cameras

The protective paints and modern coating practices used,

can make refurbishment an almost impossible task.

If your prism has mirror coating and protective paint missing, we may

be able to help. If the reflection is showing haze, but there is no damage to

the protective paint, we would not be able to help.

Please read more below if interested.

IMPORTANT INFORMATION REGARDING CAMERA PRISMS

Prisms from cameras made up to about 1970, are usually not a problem.

After that date it seems plastic/resin based protective coverings became more

widely used to protect the coatings.

These we find almost impossible to remove. We can only wait for the

acid paste we apply to creep through the damaged part of the coating.

We have customer's prisms showing very little change after more than a year.

We could not therefore advise you how long it would l take to remove the

protective 'paint'.

If we feel we can help, turn around time seems to average at least a year.

Also please be advised that we vacuum coat items with pure aluminium.

Again if you require a silver coating, this is a different process

and not possible for us. (Silver reflects about 5% more light )

 

Ground Glass Screens

We can also make custom ground glass screens for tele-cine devices and camera POA
