The smallest divergence of the HPLS-36 with OH36-60x140-210 is the ratio of the light emitting chip size to the focal length:
in 140EFL mode: divergency = 1.4mm/140 = 10mrad
in 210EFL mode: divergency = 1.4mm/210 = 6.7mrad
10 mrad corresponds to a beam size increase of 1 cm per 1 meter of distance.
The smallest spot at 1 meter is the chip size x magnification (~ratio of distance / EFL): 1.4mm x 1000mm/140mm = 10mm for 140mmEFL
1.4mm x 1000mm/210mm = 7 mm for 140mmEFL
The beam spread angle is adjustible from a collimated beam to the cone with NA= 0.2
