Description
This is an old but in perfect working and in reasonablecosmetic condition HeNe laser head, type 1105P, made by Uniphase (now Lumentum) in USA, on Jan. 1987, together with a small power supply type 05-LPL-370-065, made by Melles Griot, USA, on Feb. 1992 (pictures #1, #2).The laser head is a metallic, cylindrical tube enclosure, 38 mm dia. x 373 mm length (pictures #3 - #5). The power supply (pictures #6 - #8) although used, works perfectly with this laser.
The key switch was replaced with a new one, with two keys
. Both the laser head together with the power supply were professionally tested for long time operation. After warm-up time (cca. 20 min.) the laser delivers a measured output power of over 6.0 mW (pictures #9 - #12 for measurements; note that the measuring equipment is not for sale).
This value exceeds the originally nominal output power of 5 mW of the laser (for more technical data see the identical laser renamed 1125/P by Lumentum).
This value of the beam power represents a laser hazard class 3B (for HeNe lasers with powers between 5 mW - 500 mW). The output beam is linearly polarized with a min. 500:1 extinction ratio. This laser can be best used for educational experiments in optics, as holography, interferometry, fiber optics, laser beam characterization, polarization measurements, or as a nice, vintage collectible item of laser history. Explanation of pictures: #1, #2 - what you buy and get - three items: the laser head, the power supply with two keys, and the mains cable; #3 - #5 - images of the laser head and its labels; #6 - #8 - images of the of the power supply; #9 - #12 - measurements of the output power with professional laboratory equipment; #9, #10 - nulling the detector; #11, #12 - measuring the output power - full laser power displayed. Great tool for professionals or hobbyists.
