Precautions
Mini-spectrometers
This document describes general precautions for using Hamamatsu mini-spectrometers.
If the product comes with special precautions on the delivery specification sheet, then be sure to strictly
comply with those instructions.
1. All models
Mini-spectrometers (hereafter "the product") are high precision optical components. Do not apply excessive
vibration and shock to the product. Avoid operating and storing it in dusty locations or in areas exposed to
water, high temperature or high humidity.
When cleaning the enclosure, wipe it with a clean, soft, dry cloth. Do not use organic solvents such as
thinner and acetone.
Do not apply excessive force to the connector. Doing so may cause a poor connection or damage the
connector.
Use the product at incident light levels that do not cause the A/D count of each pixel to become saturated.
Correct measurement may not be possible when some pixels become saturated. Set a shorter integration
time if the A/D count is saturated. If the integration time cannot be shortened, we recommend you use a
neutral density filter.
Even when no light is input, the product generates an output consisting of an offset component and dark
signal. The offset component is not dependent on integration time, but the dark signal is dependent on it.
Coefficients for converting image sensor pixel numbers into wavelengths are described in the final
inspection sheet that comes with each product. For module types, those coefficients are also written into the
EEPROM in the mini-spectrometer. However, we do not provide coefficients for converting the output value
of each pixel to a value proportional to the incident light level.
2. Module type
The optical connector is exposed to outside air, so when not using the product for extended periods, place a
cap on the optical connector or connect the input optical fiber to the connector. When connecting the optical
fiber, clean the ferrule on the optical fiber as needed.
Power supplied through a USB port from a PC is limited to 5 V/500 mA per port due to USB specifications. So
power exceeding this limit cannot be supplied to the product. If connecting two or more products to one
USB port via a hub, use a hub with a power supply.
Evaluation software differs according to the product model. Be sure to install the evaluation software that
supports the product you will be using.

- Page 1 Precautions Mini-spectrometers This document describes general precautions for using Hamamatsu mini-spectrometers. If the product comes with special precautions on the delivery specification sheet, then be sure to strictly comply with those instructions. 1. All models Mini-spectrometers (hereafter “the product”) are high precision optical components. Do not apply excessive vibration and shock to the product.
- Page 2 Never connect the product to the PC before installing the evaluation software into the PC. This might prevent correctly installing the evaluation software. ® ® The supported OS is Microsoft Windows . Refer to the datasheet or operation manual for details on versions and platforms.
- Page 3 3. Head type The electrical terminals of the head type are connected to the internal image sensor signal terminals. Take the following precautions on static electricity management, circuit board design, and handling, etc. 3-1. Static electricity management Electrostatic sensitive products come with an electrostatic warning label on the product packing. Handling of the product requires taking precautions on the following points to avoid product damage and deterioration due to static electricity.
- Page 4 ● Peripheral devices must be properly grounded so that no surges are applied to the product by a leakage voltage. Do not allow a voltage exceeding the absolute maximum ratings to be applied to the product from the measurement instrument, etc. (This tends to occur during ON/OFF switching of power sources, so use caution.) If there is the possibility of a surge voltage, insert a filter (made up of a resistor and capacitor) to protect the product.
- Page 5 (1) Circuit board surface to mount a mini-spectrometer The circuit board surface to mount a mini-spectrometer should be inside an optical system that blocks external light. So, attaching variable resistors, etc. to the back side of the circuit board surface makes it easier to adjust them.
- Page 6 (8) Others Noise generated from mechanically driven sections, etc. in equipment, into which the product and circuit board are incorporated, may enter the output signal. Perform the circuit board shielding securely. Characteristics may deteriorate during operation at high temperature. Take heat dissipation measures as required.
- Page 7 Take precautions to protect the window from contamination or scratches when packing or shipping equipment in which the product is installed. (2) Precautions when mounting The product is a precision optical component, so placing excessive loads on the package may cause problems such as package warping or damage, chip peeling, wire breakage, damage to thermoelectric cooler, or poor optical characteristics.
- Page 8 Do not let the soldering iron directly contact the package section of the product. Direct contact with the soldering iron may cause mechanical or optical damage. Storage Avoid exposure to direct sunlight, harmful gases, or dust, or storage in a place with sudden temperature changes.
