    1625 nm, according to ordered wavelength. Emitted optical power: up to 50 mW, according to ordered output power! Numerical aperture of the beam 0.11. CAUTION – The use of optical instruments with these products will increase eye hazard!! ______________________________________________________________________________________________________ © 2010 Thorlabs...
  • Page 7 Safety _________________________________________________________________________________ Attention The laser modules supplied by Thorlabs are class 1M laser systems. However, if you collimate or focus the laser beam you will create a class 3R or class 3B laser system! In that case additional safety measures have to be observed!
  • Page 8 PRO8000, PRO8000-4 or PRO800. All modules must only be operated with duly shielded connection cables. Only with written consent from Thorlabs may changes to single components be carried out or components not supplied by Thorlabs be used. This precision device is only dispatchable if duly packed into the complete original packaging including the plastic form parts.
