In this post, you can read about our compact DISB electronics specifically developed with OEM instrument makers in mind.
If you have any questions about our spectrometer electronics, you are always welcome to contact us to learn more and maybe arrange a free demo.
DISB spectrometer electronics
DISB (Digital Image Sensor Board) is Ibsen’s own developed OEM spectrometer electronics. It comes with an SPI interface, which makes it ideal for fast and easy integration into your instrument. It offers fast readout – up to 600 Hz for 2048 pixels – and accurate timing control in 200 nanosecond steps with only 10 nanosecond jitter.
DISB helps instrument integrators avoid the hassle of developing an analog electronics interface and offers detector array control, analog to digital conversion (16 bit), fast SPI interface, on-board storage of calibration, and also hardware and software triggering options.
SPI is the new orange in spectroscopy
The Serial Peripheral Interface (SPI) is an interface bus commonly used to exchange data between two devices – a master and a slave, these devices being microcontrollers (master) and small peripherals such as a spectrometer (slave).
SCLK: Serial Clock
MOSI: Master output Slave input
MISO: Master input Slave output
SS: Slave Select
An SPI operates in full-duplex mode, meaning that data can be transferred in both directions at the same time. It uses separate clock and data lines dictated by the master, along with a select line to choose the device you wish to talk to.
Many compact spectrometers come with a USB interface, which is well suited for using the spectrometer in the lab to connect it to your laptop. However, for integration with a microprocessor inside a spectroscopic instrument, the SPI interface is ideal as most microprocessors will have a built-in SPI interface and can act as a master. In contrast, a USB interface would require an extra chip in your board.
Supported detectors
Ibsen’s new DISB line of electronics supports the S11639 CMOS and S11156 BT-CCD detector arrays from Hamamatsu. More detectors will be added to the list in the future.
