STC-428-P provides extremely high sensitivity, low noise 7 megapixel imaging with support for commonly-available UBVRI filter sets.<\/p>\n
The STC-428-P is the ideal package for photometry, featuring:<\/p>\n
The new STC-428-P scientific CMOS camera represents a major improvement over CCD technology.\u00a0 Compared with previous CCD models such as the STF-8300M, the STC-428-P features higher sensitivity (78% QE versus 56%), significantly lower read noise (2.5 e- versus 9.3 e-), and 20X faster readout.<\/p>\n
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.\u00a0 The built-in\u00a0StackPro\u2122<\/strong>\u00a0capability can automatically divide your exposure into up to 16 shorter sub-exposures, and stack them inside the camera prior to download.\u00a0 This dramatically increases dynamic range without imposing greater processing requirements on the host computer \u2013 with read noise equal to or lower than comparable CCD cameras.<\/p>\n Our\u00a0SmartCooling\u2122<\/strong>\u00a0active regulation maintains the sensor temperature to within 0.1\u00baC, and minimizes fan speed based on heat sink temperature for longer life and quieter operation.<\/p>\n Sensor Specifications:<\/strong><\/p>\n The STC-428-P supports several optional gain modes:<\/p>\n The STC-428-P scientific CMOS camera features\u00a0StackPro\u2122<\/strong>, a revolutionary feature that performs image stacking inside the camera.<\/p>\n While the IMX428 sensor has dynamic range on a par with its CCD predecessor, it is limited to 12 bit data (0-4095).\u00a0 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.\u00a0 As great as this sounds it does result in a lot of extra disk usage and post-processing.<\/p>\n StackPro\u2122 performs the stacking automatically, inside the camera.\u00a0 It automatically subdivides your exposure into up to 16 individual sub-exposures, and stacks them inside the camera prior to download.\u00a0 This eliminates the excessive amounts of data cluttering up your hard drive.<\/p>\n As an example, by stacking 16 sub-exposures inside the camera you can get:<\/p>\n For comparison, our STF-8300M CCD camera sports typical read noise of 9.3 e-, with a full well depth of 25,000 e-.\u00a0 In the medium gain 16X stack mode, the STC-428-OEM has similar read noise and yet has over six times the dynamic range!<\/p>\n The STC-428-P page includes an FW8-STC.\u00a0 This wheel supports standard unmounted 36 mm filters.\u00a0 To enable the use of less-expensive and commonly-available 1-1\/4\u2033 mounted UBVRI filters, a set of five\u00a010105 36 mm to 1-1\/4\u2033 Mounted Filter Adapters<\/a>\u00a0is included with the package.<\/p>\n Also included is an opaque \u201cfilter\u201d, which acts as a dark frame shutter for efficient image calibration. The camera will automatically select filter slot 8 when a dark frame is requested.\u00a0 This eliminates the extra cost and complexity of a separate mechanical shutter.\u00a0 If an eighth filter is needed then the dark frame feature can be disabled.<\/p>\n The STC-428-P comes with MaxIm LT software, which provides complete camera control and image calibration functions.\u00a0 MaxIm LT can also be upgraded to MaxIm DL Pro for full photometric analysis capability.<\/p>\n\n
