Breakthrough: Long, Thin Pixels Revolutionize Spectrometer Sensor Sensitivity

Hamamatsu Photonics, a leading manufacturer of optical sensors and instruments, has recently introduced a pair of linear CMOS image sensors designed to enhance sensitivity in spectrometers without compromising resolution.

The innovative design of these sensors includes long thin pixels, which enable efficient light collection even with shorter integration times. This breakthrough technology allows the sensors to surpass conventional CMOS in the vacuum ultra-violet (VUV) region, exhibiting remarkable sensitivity from 140 to 1,000nm.

Both sensors are packaged in a 42mm long through-hole DIP package, featuring a 28.7mm long and 0.2mm wide linear array. The S11639N-02 model consists of 2,048 14 x 200µm pixels, offering a sensitivity of 1,300 V/lx/s and a noise level of 16e-rms. On the other hand, the S13496N-02 model boasts 4,096 7 x 200μm pixels, providing a sensitivity of 650V/lx/s and a noise level of 20e-rms.

Both sensors operate from a single 5V rail with a current consumption of approximately 40mA. They are capable of outputting data at up to 10MHz. While there is no window in front of the sensing array, the sensors are protected during shipping and assembly with a glass slip cover.

These new linear CMOS image sensors support variable integration time through an electronic shutter. Additionally, the built-in timing generator allows for operation with only start and clock pulse inputs. With a wide operating temperature range of -40 to +65°C, cooling is not required for these sensors.

For ease of use, driver boards are available for purchase separately. These boards include a 16-bit ADC and a USB interface that supplies power and handles data.
