Light from a fiber enters the optical bench through the SMA 905 connector. The SMA 905 bulkhead provides a precise locus for the end of the optical fiber, entrance slit, absorbing filter and fiber clad mode aperture.

Light passes through the installed slit, which acts as the entrance aperture. Slits come in various widths from 5 µm to 200 µm. The slit is fixed in the SMA 905 bulkhead to sit against the end of a fiber. 

Slit Description Pixel Resolution
SLIT-5 5-µm wide x 1-mm high ~1.5 pixels
SLIT-10 10-µm wide x 1-mm high ~2.0 pixels
SLIT-25 25-µm wide x 1-mm high ~2.5 pixels
SLIT-50 50-µm wide x 1-mm high ~4.2 pixels
SLIT-100 100-µm wide x 1-mm high ~8 pixels
SLIT-200 200-µm wide x 1-mm high ~15.3 pixels

Back to Top

If selected, an absorbance filter is installed between the slit and the clad mode aperture in the SMA 905 bulkhead. The filter is used to limit bandwidth of light entering the spectrometer. Filters are installed permanently.

The collimating mirror is matched to the 0.22 numerical aperture of our optical fiber. Light reflects from this mirror, as a collimated beam, toward the grating. You can opt to install a standard mirror or a UV absorbing SAG+ mirror.

Back to Top

We install the grating on a platform that we then rotate to select the starting wavelength you’ve specified. Then we permanently fix the grating in place to eliminate mechanical shifts or drift.

This mirror focuses first-order spectra on the detector plane. Both the collimating and focusing mirrors are made in-house to guarantee the highest reflectance and the lowest stray light possible. You can opt to install a standard or SAG+ mirror.

The Maya2000 Pro is available with a back-thinned uncooled 2D array Hamamatsu detector. Depending on the application, you can specify the S10420 detector, which is responsive from 200-1100 nm, or the S11510 detector, which is responsive from 780-1180 nm.

Application Criteria Recommended Detector Sample Applications
VUV measurements (<~190 nm)  Hamamatsu S10420  

  • Analysis of VUV emission sources
  • Determination of plasmas used in semiconductor processing
UV-Vis measurements (~190-600 nm) Hamamatsu S10420
  • UV absorbance of plasmas and gases
  • Low light level applications such as fluorescence
Vis-NIR measurements (~800-1100 nm) Hamamatsu S11510
  • Raman
  • Low light level VIS-NIR experiments
  • SW-IR feasibility studies of various samples
