Contact Exposure Frame - High-speed Vacuum System, Excellent Light Source, Secondary Exposure, Oil Less Pump, Precision Light Meter, Easy Operation

Following are the salient features of Contact Exposure Frame:

U Two-step high-speed Vacuum System

Two-step high-speed vacuum-exhausting system of contact exposure frame can make vacuum-exhausting operate from the center and spread all round, thus ensuring a 70% higher speed than average exposure frame. (Plate of any material is ready to expose within one minute)

U Excellent Light Source (Ushio or Philip)

High quality reflection board with strong reflecting light, which is verified to be more than 86% uniformity. Good-quality violet light source, whose wavelength is 365-420NM, is three times the light intensity as average ones. High exposing quality and long time duration. Anti-electrostatic rubber cloth and block gine with strong air-tightness and durability.

U Secondary Exposure System

Secondary exposure system can wipe out dirty spots and imprints of the block gine efficiently, thus reducing retouch work and raise the efficiency of work.

U Oil Less Vacuum Pump

Best quality oil less vacuum pump runs noiselessly and lasts without maintenance.

U Precision Integrating Light Meter

Accurate integrating light meter automatically detects the light intensity of the light source, so as to accurately keep the error range within 2% and eliminate the distortion of screen dots caused by the deterioration of lamps, instability of voltage, etc.

U Easy Operation and Long Operation Life

The screen can display 5 sets of data. The CPU can store 99 sets of data.
