Each kit provides approximately 2.2 m (7.2') of overhead clearance when mounted, has continuous tracking for uninterrupted movement of the curtains, and includes enough laser safety curtains to fully enclose the optical table. All laser safety curtains are floor length, flame retardant, 2.1 m (7.0') long, and include magnetic connectors for light-tight seals. Kits with item numbers ending in 'N' or 'W' are designed with a walkway between the optical table and curtain; see the drawings below for details. This additional space allows for work to continue while the laser curtains remain closed.
All laser safety curtains are certified to EN 12254:2012(B)*; certification levels can be found in the Certifications tab. Each curtain is made using a rubber compound fabric and includes a 380 mm x 280 mm document pocket on the front of the curtain. The back of the curtain includes the item #, safety compliance information, manufacturing date, and protection level information.
Curtain end stops as well as replacement wheel runners and T-nuts are also available below. End stops provide a hard stop for a laser safety curtain mounted on the track. A laser safety valance panel and associated hardware mountings kit are available separately below. The valance panel is designed to cover any gaps near the ceiling or the curtain tracks of a laser curtain kit.

Laser Safety Curtain Kit Assembly
The animation below provides a simplified illustration of how the TFL1020B Curtain Kit is installed onto a TFS201 Overhead Shelf that was mounted onto a TF1020A7 Nexus® Table Frame. The steps in the assembly process are the same when mounting a kit onto a free-standing shelving unit. Enough laser curtains are included with each kit to fully enclose the optical table.
The animation shows the curtain kits being attached to the table frame using our TFLA01 adapter kit, which is needed to attach the kit to legacy shelving units. Our current shelving units (sold approximately after March 2017) have two Ø10 mm through holes in the top bar of each shelf support that allow the curtain kit to be directly connected using the included M8 bolts, without the use of the TFLA01. See the bottom of the page for details. Note that installing the curtain kit using the TFLA01 requires temporarily removing some of the screws that support the overhead shelf, so be sure that the shelf and optical table are empty before beginning the curtain installation.
Complete assembly instructions are provided in the manual for each curtain kit, which can be accessed by clicking on the red Docs icon (

Laser Safety and Classification
Safe practices and proper usage of safety equipment should be taken into consideration when operating lasers. The eye is susceptible to injury, even from very low levels of laser light. Thorlabs offers a range of laser safety accessories that can be used to reduce the risk of accidents or injuries. Laser emission in the visible and near infrared spectral ranges has the greatest potential for retinal injury, as the cornea and lens are transparent to those wavelengths, and the lens can focus the laser energy onto the retina.

Safe Practices and Light Safety Accessories
- Laser safety eyewear must be worn whenever working with Class 3 or 4 lasers.
- Regardless of laser class, Thorlabs recommends the use of laser safety eyewear whenever working with laser beams with non-negligible powers, since metallic tools such as screwdrivers can accidentally redirect a beam.
- Laser goggles designed for specific wavelengths should be clearly available near laser setups to protect the wearer from unintentional laser reflections.
- Goggles are marked with the wavelength range over which protection is afforded and the minimum optical density within that range.
- Laser Safety Curtains and Laser Safety Fabric shield other parts of the lab from high energy lasers.
- Blackout Materials can prevent direct or reflected light from leaving the experimental setup area.
- Thorlabs' Enclosure Systems can be used to contain optical setups to isolate or minimize laser hazards.
- A fiber-pigtailed laser should always be turned off before connecting it to or disconnecting it from another fiber, especially when the laser is at power levels above 10 mW.
- All beams should be terminated at the edge of the table, and laboratory doors should be closed whenever a laser is in use.
- Do not place laser beams at eye level.
- Carry out experiments on an optical table such that all laser beams travel horizontally.
- Remove unnecessary reflective items such as reflective jewelry (e.g., rings, watches, etc.) while working near the beam path.
- Be aware that lenses and other optical devices may reflect a portion of the incident beam from the front or rear surface.
- Operate a laser at the minimum power necessary for any operation.
- If possible, reduce the output power of a laser during alignment procedures.
- Use beam shutters and filters to reduce the beam power.
- Post appropriate warning signs or labels near laser setups or rooms.
- Use a laser sign with a lightbox if operating Class 3R or 4 lasers (i.e., lasers requiring the use of a safety interlock).
- Do not use Laser Viewing Cards in place of a proper Beam Trap.
Laser Classification
Lasers are categorized into different classes according to their ability to cause eye and other damage. The International Electrotechnical Commission (IEC) is a global organization that prepares and publishes international standards for all electrical, electronic, and related technologies. The IEC document 60825-1 outlines the safety of laser products. A description of each class of laser is given below:
| Class | Description | Warning Label |
|---|---|---|
| 1 | This class of laser is safe under all conditions of normal use, including use with optical instruments for intrabeam viewing. Lasers in this class do not emit radiation at levels that may cause injury during normal operation, and therefore the maximum permissible exposure (MPE) cannot be exceeded. Class 1 lasers can also include enclosed, high-power lasers where exposure to the radiation is not possible without opening or shutting down the laser. |  |
| 1M | Class 1M lasers are safe except when used in conjunction with optical components such as telescopes and microscopes. Lasers belonging to this class emit large-diameter or divergent beams, and the MPE cannot normally be exceeded unless focusing or imaging optics are used to narrow the beam. However, if the beam is refocused, the hazard may be increased and the class may be changed accordingly. |  |
| 2 | 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. This category only applies to visible radiation (400 - 700 nm). |  |
| 2M | Because of the blink reflex, this class of laser is classified as safe as long as the beam is not viewed through optical instruments. This laser class also applies to larger-diameter or diverging laser beams. |  |
| 3R | Class 3R lasers produce visible and invisible light that is hazardous under direct and specular-reflection viewing conditions. Eye injuries may occur if you directly view the beam, especially when using optical instruments. Lasers in this class are considered safe as long as they are handled with restricted beam viewing. The MPE can be exceeded with this class of laser; however, this presents a low risk level to injury. Visible, continuous-wave lasers in this class are limited to 5 mW of output power. |  |
| 3B | Class 3B lasers are hazardous to the eye if exposed directly. Diffuse reflections are usually not harmful, but may be when using higher-power Class 3B lasers. Safe handling of devices in this class includes wearing protective eyewear where direct viewing of the laser beam may occur. Lasers of this class must be equipped with a key switch and a safety interlock; moreover, laser safety signs should be used, such that the laser cannot be used without the safety light turning on. Laser products with power output near the upper range of Class 3B may also cause skin burns. |  |
| 4 | This class of laser may cause damage to the skin, and also to the eye, even from the viewing of diffuse reflections. These hazards may also apply to indirect or non-specular reflections of the beam, even from apparently matte surfaces. Great care must be taken when handling these lasers. They also represent a fire risk, because they may ignite combustible material. Class 4 lasers must be equipped with a key switch and a safety interlock. |  |
| All class 2 lasers (and higher) must display, in addition to the corresponding sign above, this triangular warning sign. |  |

The valance panel is available from stock in dimensions of 1.2 m wide by 0.4 m high and can be overlapped to cover the required area.
A separate hardware kit allows for the valance panels to be mounted on the curtain tracks of a laser curtain kit. The LPCVH1 Track Mounting Kit comes with 10 mounting clips to support the valance panels, as well as 10 connector clips which allow the valance panels to be securely overlapped to prevent gaps in coverage. It is recommended that at least two mounting clips are used to support each valance panel, with an additional clip used when installing the panels on a curved track, allowing for the installation of up to five valance panels. To attach the mounting clips to the curtain tracks the kit includes 20 M4 drop-in T-nuts, which can be inserted into the side channel of the curtain tracks. These T-nuts accept the included M4 cap screws; two screws can be used to secure one mounting clip, which can then be used to help support the valance panels. Please see the manual for detailed mounting instructions.
When ordering valance panels, we recommend allowing for an overlap of at least 10 cm between panels to prevent light leakage; if using the connector clips, an overlap of 15 cm is needed to allow the rigid support bars in each valance panel to overlap. An additional hardware kit designed for use with our LPC02 mounting rods is available with our laser curtain systems.
*DISCLAIMER
The laser safety valance material has been tested by a third party using EN specifications; see the Certifications tab for details. Due to manufacturing variances, mechanical wear, and laser damage, Thorlabs assumes no responsibility for laser safety fabric failure. Please consult your local laser safety specialist before purchasing to ensure that the fabric is suitable for your application. To minimize risk, inspect the fabric before each use and ensure that it is in excellent condition.
