About this product
Part Number: PF0037
Calibration of a wavelength spectrum requires observing the spectrum of a calibration light. I.e. a light with many emission lines whose wavelength is perfectly known. Such a lamp can be placed in front of the telescope, but the Alpy Calibration Module is easier and more efficient.
The calibration module incorporates an Argon-Neon lamp, whose spectrum is well known and a flat lamp (halogen lamp, with a continuous spectrum).
- argon/neon lamp for wavelength calibration
- tungsten lamp (halogen) for a continuous spectrum (flat)
- remote control possible (with separate power supplies)
- light weight: 300g
- compact: 100x95x30mm
- power supply 12V / 1A / connector 5.5 mm x 2.5 mm, + in the centre, not supplied.
When one of the lamps is lit, a small screen is placed in the telescope beam (controlled by a servo motor): the calibration or flat light then illuminates the slot of the spectroscope under conditions very close to the telescope.
In addition, you can turn off the lights and leave the screen in place, which obstructs the telescope's beam: you can make dark images without obstructing the telescope.
The calibration module must be powered with 12V - 1A minimum.
The set is remotely controllable: two connectors allow each lamp to be controlled separately (a 12V voltage on these connectors has the same effect as activating the switches).
