405nm 200mW Blue Violet Dot Laser Module

The 405nm 200mW Blue Violet Dot Laser Module is a compact high-output violet 

laser module designed for laser positioning, alignment and optical equipment applications.

Featuring a20×60mm cylindrical housing, 

this 405nm laser module produces a visible blue-violet dot beam with an elliptical spot shape. 

The standard configuration usesadjustable focus, allowing the laser spot to be optimized according to the required working distance.

The optical output power isless than 200mW, 

while other power levels can be customized according to application requirements.
