| | | Components of the "QE" Optical Bench T] Longpass Absorbing Filter: If selected, an OF-1 absorbance filter is installed between the slit and the clad mode aperture in the SMA905 bulkhead. The filter is used to block second- and third-order effects. | 4 | Collimating Mirror: specify standard or SAG+ 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. Opt to install a standard mirror or a SAG+UPG-HR mirror. | 5 | Grating: specify grating 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. | 6 | Focusing Mirror: specify standard or SAG+ This mirror focuses first-order spectra on the detector plane and sends higher orders to light traps built into the optical bench. Both the collimating and focusing mirrors are made in-house to guarantee the highest reflectance and the lowest stray light possible. Opt for a standard mirror or a UV-absorbing SAG+UPG-HR mirror. | | |

| | | |~1~| SMA 905 Connector Light from a fiber enters the optical bench through the SMA 905 Connector. The SMA905 bulkhead provides a precise locus for the end of the optical fiber, fixed slit, absorbance filter and fiber clad mode aperture. | 2 | Fixed Entrance Slit: specify slit size Light passes through the installed slit, which acts as the entrance aperture. Slits are available in widths from 5 urn to 200 urn. Each is permanently fixed to the SMA905 bulkhead. (Without a slit, a fiber acts as the entrance aperture.) | | |
| | | | 7 | Detector with TE cooling The TE-cooled, back-thinned, "2D" detector provides great signal processing speed, improved signal-to-noise ratio and great native response in the UV. It generates virtually no dark noise, allowing for long integration times. r"8| OFLV Filters: optional Our proprietary filters precisely block second- and third-order light from reaching specific detector elements. | | |

| | | SMA 905 Connector A precision SMA 905 Connector aligns to the spectrometer manufacturer's entrance slit and ensures concentricity of the fiber. For an upgrade fee that includes the cost of a another connector and labor, we will replace the standard SMA 905 Connector with a different connector of your choice. | | |

| | | Fixed Entrance Slit One option available with the user-configured QE65000 Spectrometer is the size of the entrance aperture, with the width determining the amount of light entering the bench. A slit is fixed in place; it only can be changed by our technicians. | | |

| | | Longpass Absorbing Filters We offer longpass absorbing or blocking filters; each filter has a transmission band and a blocking band to restrict radiation to a certain wavelength region for eliminating second- and third-order effects. These filters are installed permanently between the slit and the clad mode aperture in the bulkhead of the SMA 905 Connector. | | |

| | | ^ Collimating & Focusing Mirrors Another bench option is to replace the standard aluminum-coated reflective mirrors with our proprietary, UV-n absorbing SAG+ Mirrors, which increase reflectance in the VIS-NIR and, in turn, increase the sensitivity of the & spectrometer. SAG+ Mirrors are often specified for fluorescence. These mirrors also absorb nearly all UV light, 6which reduces the effects of excitation scattering in fluorescence measurements. Unlike most silver-coated mirrors, the SAG+ mirrors won't oxidize. See page 16 for a spectral graph illustrating SAG+ reflectivity. _ SAG+UPG-HR: $250 | | |
