S1024DW Deep Well Spectrometer

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 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.

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.

ADC1000-USB A/D Converter

The ADC1000-USB A/D Converter is a plug-and-play high-speed A/D converter designed for hassle-free instrument-to-PC interfacing.

·          Fast USB port interface

·          Acquires data from up to 8 channels at once

·          Integration time as fast as 3 ms

An analog-to-digital converter is necessary to interface all Ocean Optics spectrometers to PCs. Using the ADC1000-USB to interface the spectrometer to a PC eliminates the need for installing A/D converters into a PC’s motherboard and for searching for available IRQs and I/O ranges. Instead, the ADC1000-USB connects to the back of an S2000-series Spectrometer and connects to a notebook or desktop PC via a 1-meter USB cable (included). Additionally, the ADC1000-USB can be stacked or rack-mounted with the spectrometer in the same housing.

·                      Versatile Interface Options. Allows you to interface the spectrometer to a desktop, notebook or handheld PC via the USB port or to a PLC via the serial (RS-232) port

·                      Multiple Setup Options. The ADC-1000 USB can be attached directly to the back of an S2000-series Spectrometer or stacked or rack-mounted with the spectrometer in the same housing

·                      1 MHz Sampling Frequency. Enables spectrometer integration times as fast as 3 milliseconds

·                      Channel Rotator Function. Allows simultaneous acquisition of data from up to 8 spectrometer channels

·                      No External Power Requirements. When the USB port is utilized, the spectrometer and ADC1000-USB draw their power from the computer to which they are connected

Serial Interface Option. The ADC1000-USB also has a serial port for interfacing the spectrometer to PCs, PLCs and other devices that support the RS-232 communication protocol. When using the serial port on the ADC1000-USB, a separate serial cable and power supply must be specified, as they are not included with the ADC1000-USB. The serial port on the ADC1000-USB can also be used to interface an S2000 to a handheld PC running Windows CE 3.0. A different serial cable is required for spectrometer-to-handheld PC interfacing.

Storing Wavelength Calibration Coefficients. Each spectrometer has unique wavelength calibration coefficients that are necessary for calibrating the wavelength of the spectrometer. With the ADC1000-USB, you can permanently store these values onto an EEPROM memory chip in the ADC1000-USB.

High-speed Data Processing. The ADC1000-USB has 1 MHz sampling frequency for high-speed data processing. Because the integration time of Ocean Optics spectrometers is a function of each A/D converter's sampling frequency, the fastest S2000 Spectrometer integration time possible with the ADC1000-USB is 3 milliseconds, well within the parameters required for most applications. (At the opposite extreme, the longest possible integration time is 60 seconds.)

Channel Rotator Function. The ADC1000's channel rotator permits acquisition of pixels from alternating channels. For example, acquisition with a triple-channel spectrometer can be configured so that Pixel #0 is acquired from the master channel, Pixel #1 is acquired from the first slave channel, and Pixel #2 from the second slave channel. As the sequence repeats, Pixel #3 is acquired from the master channel, and so on. As a result, spectra are acquired from multiple spectrometer channels simultaneously, making the ADC1000 ideal for applications involving pulsed light sources and transient spectral events. The data collected when using the multi-channel scanning capability of the ADC1000-USB can be separated into individual spectra by a variety of Ocean Optics software products.

Operating Systems. When using the USB port on the ADC1000-USB to interface the spectrometer to a desktop or notebook PC, you must have a Windows 98/Me/2000/XP operating system. Using the serial port on the ADC1000-USB to interface the spectrometer to a desktop or notebook PC requires any 32-bit Windows operating system.

D-2000 Deuterium Light Sources

The D-2000 Deuterium Light Source produces a powerful, stable output from 215-400 nm. In addition, deep-UV versions of the light source are available, providing a wavelength range of 190-400 nm. This powerful and stable lamp provides peak-to-peak stability of less than 0.005% and drift of only +/-0.5% per hour.

Features

·          UV Coverage. Covers spectral range of 215-400 nm and has deep-UV option for 190-400 nm

·          Shutter Option. Operate an accessory shutter automatically via software

·          Great Performance. Provides an extremely stable source, with peak-to-peak stability of <0.005%

Options and Accessories

Integrated shutters are also available with the D-2000 and can be driven by a TTL signal. All versions of the D-2000 have an SMA 905 Connector for easy coupling to our spectrometers and fiber optic accessories, a safety shutter for blocking the light when the fiber is not attached, and safety goggles. The 1,000-hour deuterium bulb used in the D-2000 can be replaced easily.

Shutter Option

You can opt to purchase a D-2000 with an electronic shutter that can be driven via a TTL signal. A toggle switch on the front of the lamp and a port on the back of the lamp allow for manual or electronic shutter control.

Optical Fibers

We recommend using our solarization-resistant optical fibers with all versions of the D-2000.
