Absolute maximum ratings

Parameter	Symbol	Value	Unit
Operating temperature*1	Topr	-5 to +50	°C
Storage temperature*1	Tstg	-20 to +70	°C

*1: No dew condensation
When there is a temperature diﬀerence between a product and the surrounding area in high humidity environments, dew condensation may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability.
Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings.

Evaluation software (accessory)

By installing the evaluation software (FPIModuleEvaluation.exe) into a PC, you can perform the following basic operations.
⸱ Acquire, save measurement data
⸱ Set measurement conditions
⸱ Set built-in lamp
⸱ Acquire module information
(type number, serial number, spectral response range, etc.)
⸱ Display graphs
⸱ Calculation functions
Comparison with the reference data (reflectance, absorbance, etc.)
Note: Up to eight spectroscopic modules can be connected to a single PC and used.
Compatible OS: Microsoft® Windows® 10 (32-bit, 64-bit)
A DLL for controlling the hardware is available.
The DLL and sample software is created in the following development environment, so users can develop original measurement programs.
DLL: Microsoft Visual Studio® 2017 Visual C++®
Sample software: Microsoft Visual Studio 2017 Visual C#®

Connection examples

Reflected light measurement

Place cloth, plastic, etc. on the window material of the spectroscopic module connected to a PC via USB. The light from the light source built into the spectroscopic module strikes the object, and the spectroscopic module measures the reflected light.

Transmitted light measurement

When measuring transmitted light, a light source must be prepared (the light source built into the spectroscopic module cannot be used).
