Hello
I have recently purchased a Durst CLS 300 5 x 7 enlarger. I have found the dichr oic filters to be very dusty. What would be the best way to clean them if dry co mpressed air does not? The filters are quite large and i want to be very careful , as they are expensive.
Also there are some dichroic mirrors near the lamps to direct the light to the f liters and diffusion chamber. I am assuming they reflect visible and transmit IR in order to reduce heat. The coating seems to be flaking off, as they are very close to a 1000W halogen lamp and would get very hot (i assume this is why they are flaking). The unit is already fan cooled. Does anyone know of any place that may recoat these??
Thanks for any info
