OPERATING INSTRUCTIONS HARDWARE

3.1

camSPECS

Switch camSPECS on and let it run for a couple of minutes (>= 4 min) until it reaches a stable temperature.
3.2

Filter panel

A set of 39 interference filters is used to generate narrow-band light. The filters cover a range of 380 - 760
nm in 10 nm steps. The filters are mounted on the front plate of the camSPECS box. The arrangement of the
filters can be seen in the following figure. The series starts with 380 nm on the upper left side and continues
line by line to 760 nm. The neutral density (ND) filters for inhomogeneity correction are positioned in
between.

Spectrometer calibration

The calibration device for the filters is already calibrated when delivered. The device needs a recalibration
once a year, regardless of the operating hours. Please read chapter 5.1.
