Finger-tip size, ultra-compact spectrometer head integrating MEMS and image sensor technologies www.hamamatsu.com 1 Finger-tip size: 20.1 × 12.5 × 10.1 mm Weight: 5 g Spectral response range: 340 to 780 nm Color adjustment of various large size displays Spectral resolution: 15 nm max. Hermetic package: High reliability against humidity Water quality control monitors and other environment measuring instruments Installation into mobile measurement equipment Measuring instruments that use portable devices such as smartphones and tablets Wavelength conversion factor*1 is listed on final inspection sheet Color monitoring for printers and printing machines Testers for lights and LEDs Features Applications *1: A conversion factor for converting the image sensor pixel number into a wavelength. A calculation factor for converting the A/D converted count into the input light level is not provided. The C12666MA is an ultra-compact (Finger-tip size) spectrometer head developed based on our MEMS and image sensor technologies. The adoption of a newly designed optical system has achieved a remarkably small size, less than half the vol- ume of the previous mini-spectrometer MS series (C10988MA-01). In addition, the employment of hermetic packaging has improved humidity resistance. This product is suitable for integration into a variety of devices, such as integration into printers and hand-held color monitoring devices that require color management. It is also suitable for applications that collaborate with portable devices, such as smartphones and tablets.

Electrical characteristics

Parameter Min. Typ. Max. Unit Supply voltage 4.75 5 5.25 V Power consumption - 30 - mW Video rate 0.25 - 200 kHz Output impedance - 150 *4 - Ω *4: An increase in the current consumption at the video output terminal also increases the chip temperature and so causes the dark current to rise. To avoid this, connect a buffer ampli fi er for impedance conversion to the video output terminal so that the current fl ow is minimized. As the buffer amplifi er, use a JFET or CMOS input operational amplifi er of optical input impedance.

Hollow Entrance slit CMOS linear image sensor with a slit Reflective concave brazed grating Grating chip Incident light Optical component layout Besides a CMOS image sensor chip integrated with an optical slit by etching technology, the C12666MA employs a refl ective concave brazed grating formed by nanoimprint. In addition, the glass used in the light path of the previous C10988MA-01 is not used in the C12666MA, making it extremely compact.

  • The C12666MA is electrically conductive, so be careful when designing the circuit to avoid short circuit caused by contact with a circuit pattern.
  • If external force is repeatedly applied to the lead pins, this may damage the lead pins.
  • To prevent damage due to soldering, be careful of the soldering temperature and time. As a general guide, fi nish soldering within 3.5 seconds at 350 °C or less when soldering by hand, or within 10 seconds at 260 °C or less when using a solder bath.

The internal shift register starts operating at this timing. The integration time is determined by the start pulse intervals. However, since the charge integration of each pixel is carried out between the signal readout of that pixel and the next signal readout of the same pixel, the start time of charge integration differs depending on each pixel. In addition, the next start pulse cannot be input until signal readout from all pixels is completed. Video output is 1/4 of the clock pulse frequency.

Micro-spectrometer C12666MA Micro-spectrometer evaluation circuit C11351-10 (sold separately) The C11351-10 is a circuit board designed to simply evaluate the characteristics of the micro-spectrometer. The characteristics of the micro-spectrometer can be evaluated using the evaluation software by connecting the micro-spectrometer to a PC with a USB cable A9160 (AB type, sold separately)* 11. Initial evaluation circuit for micro-spectrometer*12 Wavelength conversion factors of the micro-spectrometer can be input from a PC.*13 High A/D resolution (16-bit) USB powered

Only the sensor board has been modi fi ed. If you already have the C11351, you only have to purchase the C11351-03 (the sensor board for micro-spectrometers) to evaluate C12666MA micro-spectrometers. *13: A typical wavelength conversion factor is entered at the time of shipment of the C11351-10. To measure a spectrum with higher wavelength accuracy, it is necessary to input the wavelength conversion factor listed in the fi nal inspection sheet that comes with each micro-spectrometer. Note: Since the C11351-10 is an evaluation circuit for the micro-spectrometer, the DLL function specifi cations are not available to users.
