These lasers are an ideal choice for applications that require low-power or ease of use, such as alignment or the classroom. This type of dichroic is highly transmissive below the cutoff wavelength and highly reflective above it. The HNL020RB from Thorlabs Inc is a Laser with Wavelength 632.8 nm, Power 2 W, Output Power (CW) 2 W, Operating Temperature -40 to 70 °C. The intensity stability of the HNL050LB is about 0.2%. Hello,
The search terms for any product can be seen by looking at the "Tag Cloud" tab. The IEC document 60825-1 outlines the safety of laser products. Goggles are marked with the wavelength range over which protection is afforded and the minimum optical density within that range. I'm getting electric shock from the power supply. Due to the significant ASE background, a bandpass filter should be used for precision measurements. Product Details . HNL020LB is a linearly polarized HeNe (PER of 500:1) with a fixed higher output power (2mW). This class of laser may cause damage to the skin, and also to the eye, even from the viewing of diffuse reflections. Thorlabs' line of red Helium-Neon gas lasers have stable output powers from 0.5 to 35 mW and a fundamental Gaussian beam. Thank you.

High Quality Thorlabs Logo 1000px:Save this ImageSave this Image The HCL FiberPort Adapter allows a FiberPort coupler to be attached directly to the front of a HeNe laser. The polarization state of a randomly polarized HeNe changes on nanosecond timescales; when averaged over time, the light emitted from these lasers appears randomly polarized. Each USB-equipped laser module has collimated output at 520 or 635 nm, an on/off switch, and a built-in highly attenuating electrical filter to eliminate noise in the laser output, regardless of the power supply used. Hallo,
Due to this, HeNe lasers are in greater danger of experiencing dangerous stress during handling by the end user.

Post appropriate warning signs or labels near laser setups or rooms. I would like to have the quote for the purchase of one power supply for the HNL050L laser. 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. Thorlabs' cylindrical, 5.0 mW, red (632.8 nm) Helium-Neon lasers feature a tube design that makes them easy to mount in nearly any optical system. Did I get the compatible laser head and power supply? Hi, before ordering I would like to get information about the output beam height of HNLS008R-EC. The HNLS008R-EC can also be adapted with t-nuts to attach directly to optical table bases or optical posts to adjust the height and angle of the beam. C-Band and L-Band Tunable Lasers, Benchtop. The chart in the safety tab is too vague tone able to figure out which class each of these lasers for into. Do not know other specs.
A result is that the primary cause of damage to HeNe lasers is rough handling after receipt of the laser. Manufacturer. During normal operation, the cavity length, and hence the power, can vary. I will reach out to you directly to discuss this further. 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. Description. Unfortunately, we cannot specify these parameters. C $60.00. Thorlabs' selection of tunable lasers includes benchtop external cavity diode lasers with wide tuning ranges, half butterfly gain chips, and spectroscopy kits. However, diffuse reflections are not harmful. These hazards may also apply to indirect or non-specular reflections of the beam, even from apparently matte surfaces. Robert. Product Details .

The laser is getting heated up so much when I switch it on. Thorlabs' new search engine was designed to provide quick and accurate results that could be easily processed. Because of the blink reflex, this class of laser is classified as safe as long as the beam is not viewed through optical instruments. We have seen ~20% power drop at ~40,000 hour operating point, which is the basis of our definition of “lifetime” in this case. We expect the power to degrade by 1-2% per year, and have a 1-year warranty. We are currently working to release this laser in the near future.
