I'm getting electric shock from the power supply. The lifetime of HeNe Lasers depend on the application and the point at which the power degrades to a point where it is no longer usable in a system. These lasers are an ideal choice for applications that require low-power or ease of use, such as alignment or the classroom. HeNe lasers will provide optimum performance over a long lifetime when they are handled gently. During normal operation, the cavity length, and hence the power, can vary. HeNe Laser, 632.8 nm, 0.8 mW, Polarized, 100 - 240 VAC Power Supply. Could you provide the following information about the HNL225R-EC: Please note that these self-contained lasers do not feature a remote interlock connector or an integrated shutter. Can you send me a quote? Lasers in this class are considered safe as long as they are handled with restricted beam viewing. HeNe Laser, 632.8 nm, … I do not need the laser itself but just the power supply unit, but I could not find a quotation for it and how to order. In addition, as shown to the left, the bottom of the laser contains a groove that accepts our XE25T3 (XE25T3/M) Low-Profile T-Nuts, providing an easy way to use standard optomechanical bases to mount the laser to a breadboard or optical table. I have a HNL100L Laser and I would like to know exactly where the beam waist is located. The linearly polarized beam is polarized vertically with respect to the cable at the rear of the laser's housing. Depending upon the model, the output beam is either linearly polarized or randomly polarized (unpolarized). I had requested to have Australian power plugs but seemed fell to deaf ears. HeNe Laser, 632.8 nm, 2 mW, Random, 100 - 240 VAC Power Supply. Hello, thank you for contacting Thorlabs. Hello, we've got a 0.8mW HeNe Laser in a Lab here and I wonder about the Laser Class 3R and the precautions with safety glasses for red and so on.. Sharp 488nm … The Y-Fi laser family is unique and powerful in its ability to deliver the highest peak power in the MHz class while also being designed for ease of use and ruggedness. Class 2 lasers, which are limited to 1 mW of visible continuous-wave radiation, are safe because the blink reflex will limit the exposure in the eye to 0.25 seconds. Great care must be taken when handling these lasers. The HCL FiberPort Adapter allows a FiberPort coupler to be attached directly to the front of a HeNe laser. Because of the blink reflex, this class of laser is classified as safe as long as the beam is not viewed through optical instruments. Thorlabs offers an extensive selection of CE compliant 632.8 nm (red) Helium-Neon (HeNe) Lasers with powers from 0.8 mW to 22.5 mW from stock. They also represent a fire risk, because they may ignite combustible material. Please feel free to reach out to us at techsupport@thorlabs.com or by calling 973-300-3000 for support.
