This is a replacement heat absorbing glass for the LPL 7700 (Saunders/LPL 670XL, Omega/LPL 670XL) Dichroic or VCCE lamphouse. This heat filter eliminates much of the infrared radiation from the light produced by the enlarging lamp, thus helping to protect filters, mixing box and negatives from heat damage, and reducing the chance of negative "popping" which affects focus. This glass is approximately 40mm diameter and 3.7mm thick. |
