Mounting The Laser Beam Delivery System - NT-MDT NTEGRA Spectra Instruction Manual

4. Tighten two nuts of the guide pins (pos. 1 in Fig. 2-7) with hexagonal box wrench.
Fixing the guide pins enables the positioning device to take its initial state if it is
remounted on the base unit.
5. With the movement screws 1 and 2 (Fig. 2-9), find the position of the optical tube
where the center of the tube lens is aligned with the center of the exchangeable mount.
This completes mounting the optical tube on the base unit.

2.3. Mounting the laser beam delivery system

The LBDS connects either the laser with the optical tube for adjusting the detection
channel ar the optical tube with the PMT module for adjusting the delivery channel or for
measurements.
Here, mounting the LBDS for adjusting the detection channel is explained.

ATTENTION! Do not look through the laser exit aperture or the LBDS.
Direct or scattered laser radiation is hazardous and may cause eye injuries.
To mount the LBDS, perform the following steps:
1. Take the LBDS and insert its
(Fig. 2-10).
