S1024DW Deep-Well Spectrometers for High S:N

The S1024DW Deep Well Detector Spectrometer features a 1024-element photodiode array detector for applications requiring high signal-to-noise (S:N) measurements.

Reliably observe an change of less than 0.00001 absorbance units
Ideal for high light level applications involving solution absorbance, transmission and dissolution testing
Can be multiplexed with up to 8 spectrometer channels

The S1024DW is available for only $3002. Additional channels are just Call for Price.

The S1024DW Spectrometer has a compact optical bench coupled to a 1024-element photodiode array detector. The S1024DW accepts light energy transmitted through single-strand optical fiber and disperses it via a fixed grating across the photodiode array, which is responsive from 200-1100 nm. An SMA 905 connector allows for easy coupling to an extensive line of fiber optic light sources, probes, chemical sensors, and other spectrophotometric accessories.

The S1024DW can be multiplexed with up to 8 spectrometer channels, all of which run from a single A/D converter, the ADC1000-USB.

User's Tip: The S1024DW is our standard deep well detector spectrometer. Also available is the S1024DWX, with a detector distinguished by its large pixel size and large well depth. The S1024DWX is available on a special-order basis starting at Call for Price.

S1024DW Spectrometers Specifications

Signal-to-noise for all detectors is limited by the number of sampled photons. The S1024DW has a large well depth detector with high S:N that makes it especially useful for high light level absorbance applications.
