This 1 inch collimator can be used to collimate light from a Liquid Light Guide.
A Collimator is used to keep the output of the light guide from diverging by expanding the beam and making it more parallel. To learn more about collimators see our blog posts here.
This collimator is not adjustable and has external SM1 style threading. For application that require an adjustable lens see: Prizmatix Liquid Light Guide XYZ Collimator
For applications that need very low divergence angles, see our two inch and three inch collimators.
