Following are the salient features of Contact Exposure Frame:
Û°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)
Û°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.
Û°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.
Û°Oil Less Vacuum Pump
Best quality oil less vacuum pump runs noiselessly and lasts without maintenance.
Û°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.
Û°Easy Operation and Long Operation Life
The screen can display 5 sets of data. The CPU can store 99 sets of data.
