Hover over the numbers on the image for more info.

SMA 905 Connector
Light from a fiber enters the optical bench.

Click now for more detailed information.

Interchangeable Entrance Slit
Light passes through the installed slit, which acts as the entrance aperture.
Jaz allows you to change your entrance aperture to suit your application.

Click now for more detailed information.

Longpass Absorbing Filter
A filter has a transmission band and a blocking band to restrict radiation to a certain wavelength region for eliminating second- and third-order effects.

Collimating Mirror
Light reflects from this mirror, as a collimated beam, toward the grating.

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, fixed slit, absorbance filter and fiber clad mode aperture.

Light passes through the installed slit, which acts as the entrance aperture. Unlike the fixed slits in most spectrometers, Jaz allows you to change your entrance aperture to suit your application. Slits come in various widths from 5 µm to 200 µm and can be replaced by qualified technicians. The slit is fixed in the SMA 905 bulkhead to sit against the end of a fiber.

Slit Description Pixel Resolution
INTSMA-005 5-µm wide x 1-mm high ~3.0 pixels
INTSMA-010 10-µm wide x 1-mm high ~3.2 pixels
INTSMA-010S 10-µm wide x 50-µm high ~3.2 pixels
INTSMA-025 25-µm wide x 1-mm high ~4.2 pixels
INTSMA-050 50-µm wide x 1-mm high ~6.5 pixels
INTSMA-100 100-µm wide x 1-mm high ~12 pixels
INTSMA-200 200-µm wide x 1-mm high ~24 pixels

If selected, an absorbing 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 spectrometer or to balance color. Filters are installed permanently.

Item Description

OF1-GG375 Longpass filter; transmits light >375 nm
OF1-GG395 Longpass filter; transmits light >395 nm
OF1-GG475 Longpass filter; transmits light >475 nm
OF1-OG515 Longpass filter; transmits light >515 nm
OF1-OG550 Longpass filter; transmits light >550 nm
OF1-OG590 Longpass filter: transmits light >590 nm

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.

SAG+ mirrors are often specified for fluorescence. These mirrors also absorb nearly all UV light, which reduces the effects of excitation scattering in fluorescence measurements. Unlike typical silver-coated mirrors, the SAG+ mirrors won’t oxidize. They have excellent reflectivity — more than 95% across the VIS-NIR.

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.

Detector Collection LensThis cylindrical lens, made in-house to ensure aberration-free performance, is fixed to the detector to focus the light from the tall slit onto the shorter detector elements. It increases light-collection efficiency and reduces stray light. It also is useful in a configuration with a large-diameter fiber for low light-level applications.

Jaz features the 2048-element Sony ILX511B linear CCD array detector. Each pixel responds to the wavelength of light that strikes it. Electronics bring the complete spectrum to the software.

Our proprietary filters precisely block second- and third-order light from reaching specific detector elements.

When selected, the detector’s standard BK7 window is replaced with a quartz window to enhance the performance of the spectrometer for applications <340 nm.

Custom configured Jaz spectrometer gives you options to design the optical bench for your application. Jaz features an asymmetrical crossed Czerny-Turner optical bench, which has no moving parts that can break, and a replaceable aperture (interchangeable entrance slit) design.

Follow the guide to choose an entrance aperture size, detector accessories, filters, a grating and more, or ask our Applications Sales Engineers to help you with choosing the correct components.
