Blue Pulsed Lasers

Those our lasers are used by embossed holograms manufacturers for hologram origination.

Geolas BlueBird series lasers emit 440nm and are particularly designed to replace CW lasers in embossed holograms master originating process. Having SLM with coherence length greater than 3 meters, peak power of up to 300kW, continuous power of up to 450mW and low maintenance cost. BlueBirds are reliable replacement for HeCd CW lasers.

Description

Geolas BlueBird series pulsed lasers emit 440nm and are particularly designed to replace CW lasers in embossed holograms master originating process. Having SLM with coherence length greater than 3 meters, peak power of up to 300kW, continuous power of up to 450mW and low maintenance cost. BlueBirds are reliable replacement for HeCd CW lasers.

Because of just 50ns laser pulse duration, no vibration will affect your photoresist exposure.
