| Accessory heat absorbing glass for all Beseler condenser enlargers with the 67 Series lamphouse including the Printmaker 35, Printmaker 67, 67XLC, 67CP, 67C, 67CS, etc. The glass is mounted in a metal frame and is simply inserted in the lamphouse in the upper slot in the lamphouse as shown in the diagram in the instruction manual.
Heat absorbing glass eliminates much of the infrared radiation from the light produced by the enlarging lamp, thus helping protect the filters and negatives from heat damage, and helping to prevent negative "popping" which affects focus. |
