Product Description

QHYCCD QHY290M Monochrome COLDMOS Camera

Back-illuminated (BSI) CMOS Sensor

The QHY290 uses an extremely sensitive BSI CMOS sensor, the Sony IMX290. This sensor has very high QE, and very low (0.7e-) read noise.

128MB DDR Buffer

The QHY290 has a built-in 128MB DDRII image buffer. The benefit of the image buffer is that the memory will cache the image and transfer it to the computer when the USB interface is not busy or being interrupted, and the frame will not be lost or corrupted. This buffer also allows a slower computer with USB 2.0 socket to capture every frame without loss even if the USB socket is occasionally busy with other peripherals. This buffer also makes it possible to run multiple cameras using one computer without USB transfer problems.

Full Anti-Dew Solution

With more than a decade of experience designing cooled cameras, QHYCCD has applied this knowledge to the QHY290 camera. The full anti-dew technology includes a sealed CMOS chamber with silicon gel tube socket and a heated chamber optical window. This technology prevents dew from forming on the sensor itself, or on the chamber window, even in a high humidity environment.

The QHYCCD 3rd-Generation Color Filter Wheel

New ultra-thin stepper motor drive and fully automatic filter switching revolutionizes overall performance!

New ultra-thin hybrid stepper motor drive.

QHYCCD selected a high quality ultra-thin hybrid stepper motor for the 3rd generation filter wheel design. Compared to the PM stepper motor used in many filter wheels, the hybrid stepper motor has higher precision, smaller step angle, and is more expensive. The motor is enclosed to prevent dust from entering the motor, thus improving reliability and motor life. The direction of filter rotation can be reversed: The filter carousel can be rotated clockwise or counterclockwise to complete the rotation quickly which is very convenient. The overall design is thinner.

Friction drive with zero backlash

Regarding the evolution of the motor drive, our 2nd generation filter wheels used a gear drive while this 3rd generation filter wheel uses a friction drive that results in zero backlash during operation.

USB serial port switch.

The serial port switch can accommodate fast switching between serial communication mode and USB communication mode.

Use the USB port to power the filter wheel.

The filter wheel supports the QHY 4-pin connection control mode. The firmware is open source and compatible with Arduino. The design is compatible with the QHY-OAG (off-axis guide) for the corresponding size.

Beautiful in appearance and ingenious.

The QHYCFW3 main body is cut from a single piece of aluminum by a precision CNC machine. The craftsmanship and finish are exquisite. When you hold the small design, you do not want to put it down!

A specially designed filter carousel allows the installation of unmounted filters of different thicknesses. Mounted Filters below 10 mm thick can be installed and unmounted filters of different thicknesses can also be mounted on the same filter disc. Filter positioning is more precise and faster.
