Micro-spectrometer C12666MA Finger-tip size, ultra-compact spectrometer head integrating MEMS and image sensor technologies 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 volume 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. Features Applications Finger-tip size: 20.1 × 12.5 × 10.1 mm Color monitoring for printers and printing machines Weight: 5 g Testers for lights and LEDs Spectral response range: 340 to 780 nm Color adjustment of various large size displays Spectral resolution: 15 nm max. Water quality control monitors and other environment measuring instruments Hermetic package: High reliability against humidity Installation into mobile measurement equipment Wavelength conversion factor*1 is listed on final inspection sheet Measuring instruments that use portable devices such as smartphones and tablets *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.

To avoid this, connect a buffer amplifier for impedance conversion to the video output terminal so that the current flow is minimized. As the buffer amplifier, use a JFET or CMOS input operational amplifier of optical input impedance. www.hamamatsu.com 1 Micro-spectrometer C12666MA Structure Parameter Dimensions (W × D × H) Weight Slit*5 (H × V) NA*6 Image sensor (H × V) Number of pixels Pixel size (H × V) Specification 20.1 × 12.5 × 10.1 5 50 × 750 0.22 CMOS linear image sensor with a slit 256 12.5 × 1000 Unit mm g μm pixels μm Value +5 to +50 -20 to +70 Unit °C °C *5: Entrance slit aperture size *6: Numeric aperture (solid angle) Absolute maximum ratings Parameter Operating temperature*7 Storage temperature*7 *7: No dew condensation When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation may occur on the product surface.

Always be sure to use the product within the absolute maximum ratings. Optical component layout Besides a CMOS image sensor chip integrated with an optical slit by etching technology, the C12666MA employs a reflective concave blazed 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.

As a general guide, finish 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. 4 Micro-spectrometer C12666MA Dimensional outline (unit: mm, tolerance unless otherwise noted: ±0.2) 0.5 Slit +0.1 ϕ3.2 -0 10.91 [Top view] 12.5 0.05 × 0.75 Index mark 20.12 Slit position 10.12 2.5 18.53 3.3 ± 0.3 0.7 [Side view] 0.47 ± 0.03 7.62 ϕ1.4 ± 0.05 7.62 2.54 [Bottom view] Vdd Video GND CLK Case NC ST NC Gain EOS KACCA0336EB Pin connections Make electrical connections to an external circuit using leads.

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. 7 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)*10. Features Initial evaluation circuit for micro-spectrometer*11 Wavelength conversion factors of the micro-spectrometer can be input from a PC.*12 High A/D resolution (16-bit) USB powered *10: Compatible OS: Microsoft® Windows® 7 Professional SP1 (32-bit, 64-bit), Microsoft® Windows® 8 Professional (32-bit, 64-bit) *11: The C11351-10 is a modified version of the C11351 evaluation circuit for the previous mini-spectrometer MS series (C10988MA-01, C11708MA). Only the sensor board has been modified. 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. *12: 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 final inspection sheet that comes with each micro-spectrometer.
