Bore Sighting; Bore Sighting At 1550 Nm; Bore Sighting At 830 Nm - Safran LRF 6042 Manual

LRF 6042 Integrator Manual

4.4 Bore sighting

The module components are bore sighted in the factory. For this reason, the module can be mounted and
replaced easily with a tolerance of ± 1.5 mrad.
If higher precision is desired for a professional boresight, every individual module has to be aligned to the
host's optical axis individually.
For this procedure, we recommend the use of a collimator and a camera.
Collimators can be sourced from:
 Inframet (www.inframet.com).
 Möller Wedel Optical (http://www.moeller-wedel-optical.com).
Vendors of 1'550 nm cameras (SWIR cameras) include:
 XenICs (www.xenics.com) (e.g. XEVA-1.7-320)
 Sensors Unlimited (www.sensorsinc.com) (e.g. 640HS-1.7RT)
 Allied Vision Technologies (www.alliedvisiontec.com) (e.g. Goldeye P-008 SWIR)
 Raptor Photonics (www.raptorphotonics.com)
4.4.1

Bore sighting at 1550 nm

The LRF module provides a low power continuous lasing mode to make its line of sight visible to SWIR cameras. Please
see chapter 6.5.3 for details.
4.4.2

Bore sighting at 830 nm

LRF 6042 HP and LRF6042 LP offer an 830 nm pointer as a factory configuration, to make its line of sight
visible to NIR cameras (also Night Vision Systems and most CMOS cameras). These cameras are
significantly cheaper than SWIR cameras.
Please see chapter 8.6.4 for details.
NOTICE
If the laser pointer is too strong for the camera, the use of filter attenuators is necessary. They can
be sourced, for example, from Schott (KG1, KG2, KG3 or KG5):
