- Help in modify a BW tek BTC100-2s spectrometer to improve its resolution while decreasing the spectral range.
Hello All,
I recently purchased a BW Tek BTC100-2s spectrometer from eBay. It has fairly good specifications, but I have been wondering if there is an inexpensive way to improve its resolution. The spectrometer uses a Czerny-Turner configuration. My plan was to place a slit at the focal length where the detector (F) would be, then expand that narrow section of the spectrum to fill the detector. However, I have been struggling with how to efficiently expand and focus the light after the slit onto the detector. Here are some of the specs for the spectrometer:

- Spectral range: 400-640nm
- Slit size: 50µm
- Grating: 1800 lines/mm, blazed at 500nm
- Detector: Sony ILX511 2048 Pixel CCD
- Pixel spacing: 14µm
- Pixel size: 200µm
