The STC-428-OEM is designed to be used as a component in instruments for medical imaging, laboratory instruments, low-light industrial inspection, and other applications. The basic camera platform can be modified to meet your mechanical requirements including mounting, packaging, accessories, and more. Options such as a mechanical shutter or filter wheel can be added. Software API support is provided for a variety of operating systems including embedded Linux applications.
An evaluation kit is available, which includes all the accessories and software you need to get your evaluation up-and-running quickly. Engineering support is provided to help you with your integration process.
Problem: We need to integrate a compact, low cost, yet high performance imaging camera for our demanding low-light-level application
Solution: STC-428-OEM provides extremely high sensitivity, low noise 7 megapixel imaging in a compact, easily integrated package with complete engineering support
The STC-428-OEM is our most popular scientific CMOS camera for OEM applications such as ELISA microplate readers, colorimetry, fluorescence, and other low-light level imaging applications. The STC-428-OEM features:
For years mature CCD sensor technology, embodied in our venerable STF-83oo-OEM camera, set the standard for high sensitivity, low noise, high dynamic range, and images free of pattern noise.
The new STC-428-OEM scientific CMOS camera represents a major improvement over CCD technology. Compared with previous CCD models, the STC-428-OEM features higher sensitivity (78% QE versus 56%), significantly lower read noise (2.5 e- versus 9.3 e-), and 20X faster readout.
While a single exposure on the IMX428 sensor can equal CCD dynamic range, the combination of fast readout and very low read noise allows for stacking many shorter to produce greater dynamic range than previously possible. The built-in StackPro™ capability can automatically divide your exposure into up to 16 shorter sub-exposures, and stack them inside the camera prior to download. This increases dynamic range without imposing greater processing requirements on the host computer.
Our SmartCooling™ active regulation maintains the sensor temperature to within 0.1ºC, and minimizes fan speed based on heat sink temperature for longer life and quieter operation.
The STC-428-OEM supports several optional gain modes:
The STC-428-OEM scientific CMOS camera features StackPro™, a revolutionary feature that performs image stacking inside the camera.
While the IMX428 sensor has dynamic range on a par with its CCD predecessor, it is limited to 12 bit data (0-4095). At the same time it also has far lower read noise, which means you can stack many more shorter exposures without degrading signal-to-noise ratio. As great as this sounds it does result in a lot of extra disk usage and post-processing.
StackPro™ performs the stacking automatically, inside the camera. It automatically subdivides your exposure into up to 16 individual sub-exposures, and stacks them inside the camera prior to download. This eliminates the excessive amounts of data cluttering up your hard drive.
As an example, by stacking 16 sub-exposures inside the camera you can get:
For comparison, our STF-8300M CCD camera sports typical read noise of 9.3 e-, with a full well depth of 25,000 e-. In the medium gain 16X stack mode, the STC-428-OEM has similar read noise and yet has over six times the dynamic range!
Our engineers and programmers are available to assist you in evaluating the camera and integrating it into your equipment.
Our powerful Windows-based evaluation software helps you quickly assess the camera’s potential for your application. Our multiplatform API allows you to quickly integrate the camera into your application, whether running on desktop systems or embedded hardware. Sample code is available. Our programmers are available to assist you with integration into your application.
Customization is available. We can customize mechanical mounting, redesign or even remove the outer shell, or add options to meet your requirements. We can also build full custom hardware if required.
In addition to full custom modifications, we have standard options available including:
We can provide a customized evaluation kit upon request. Please contact us for quotation.
Our products are compliant with CE, FCC, and IC requirements. RoHS, REACH, and conflict mineral compliance documentation is available.
Diffraction Limited has been certified by British Standards Institution (BSI) to ISO 9001:2015 Quality Management under certificate number FM 719560.
