The 18mm x 123mm x 1.1mm LRGB and 3nm SHO narrowband filters are customized by XiMei Filters. The LRGB filters have an optical density (OD) value of 3, while the narrowband filters have an OD value of 5.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eSo often, compactness in astroimaging is achieved at the expense of some other critical feature found in multi-component cooled systems, such as sensor quality or thermoelectric cooling, etc. Such is not the case with the miniCAM8. Based on Sony’s IMX585 8 MP sensor, the miniCAM8 includes full TE cooling capable of reaching a delta of -45℃ from ambient along with a built-in 8-position filter wheel for complete LRGB and narrowband imaging.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe IMX585 is a Sony Starvis II processor that enables high sensitivity and high dynamic range (HDR). It also improves sensitivity in the near-infrared range by approximately 1.7 times* compared to the IMX485. The miniCAM8 has a maximum quantum efficiency of 60% in the near-infrared band and 92% in the visible wavelength band.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eOne benefit of the back-illuminated CMOS structure is improved full-well capacity. This is particularly helpful for sensors with small pixels. In a typical front-illuminated sensor, photons from the target entering the photosensitive layer of the sensor must first pass through the metal wiring that is embedded just above the photosensitive layer. The wiring structure reflects some of the photons and reduces the efficiency of the sensor.\u003c\/p\u003e\n\u003cp\u003eIn a back-illuminated sensor, the light is allowed to enter the photosensitive surface from the reverse side. In this case, the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer, and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency, the more efficient the sensor is at converting photons to electrons, and hence the more sensitive the sensor is to capturing an image of something dim.\u003c\/p\u003e\n\u003cp\u003eLinearity HDR Mode - While the native ADC of the Sony IMX585 sensor is 12-bit, QHY merged the high and low gain to extend the data to 16-bit for better dynamic range. However, since this 16-bit depth is not native, a sudden shift in linearity might occur, affecting the smooth transition in images. To address this, QHYCCD developed the “Linearity HDR” mode, which uses an algorithm-based approach to correct image linearity through software, ensuring smoother transitions and richer color representation.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eIn the “Linearity HDR” mode, the full well is 46 ke-, while the read noise is only 1.0e-; the dynamic range reaches up to 46,300:1, equivalent to 93 dB or 15.5 stops.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eThe QHY MiniCam8 also offers zero amp glow, dual-stage TE cooling, and anti-dew technology with a built-in dew heater for the optical window and a silicon gel tube socket to control humidity in the sensor chamber.\u003c\/p\u003e\n\u003cp\u003e\u003ca rel=\"noopener\" title=\"QHY MiniCam8 Information Packet (PDF)\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/files\/QHY_MiniCAM8_Information_Packet.pdf?v=1745352953\" target=\"_blank\"\u003e\u003cem\u003eRead more about the QHY MiniCam8\u003c\/em\u003e\u003c\/a\u003e...\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"display: block; margin-left: auto; margin-right: auto;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/files\/MiniCam8_WITB_Mono.png?v=1745351060\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"UTF-8\"\u003e\u003cstrong\u003e\u003cem\u003eNote: As part of the structural upgrade of the miniCAM8M, the drying system has been redesigned.
