Laser Components has released the Flexpoint Mini series laser diode modules. At only 8mm in diameter by 15mm in length, the laser diode incorporates a variable lens that can be adjusted to focus or collimate the emitted laser beam.
There are four module options available. A choice of wavelength – either 635nm or 650nm – and a choice of output power – either 1mW or 4.9mW – in each case. Protection circuits cater for surge, voltage peak and reverse voltage situations. Divergence is less than 1.5mrad and the beam diameter at the output is approx 2.5 x 0.8mm (focusable). The module operates from a supply voltage of 4.5-6VDC.
