IMAGING DETECTOR / HIGH SENSITIVITY NIR DETECTOR
InGaAs HIGH SENSITIVITY NIR DETECTOR ISA041 series
InGaAs solid state image sensing detector, having high sensitivity up to 1700nm NIR wavelength range.

InGaAs high sensitivity NIR detector is a NIR detector having high spectral sensitivity from 950nm to 1700nm wavelength range.
Especially, it has very high spectral sensitivity in 1310nm-1550nm wavelength range, so it is best for beam proﬁle measurement andanalysis, beam observation, inspection, assembling adjustment of various optical devices and modules for optical communication. In
addition, it is applicable for inspection of semiconductor device and general purpose NIR image observation.
【Example of infrared image observation using InGaAs detector】

This is an example of using a light source of 1550 nm
and observing an infrared beam spot of about 10 μmφcollected by the light collection module.
●Optics: NFP measurement optics M-Scope type S●Objective lens: M-Plan Apo NIR 100x
●Detector: InGaAs high sensitivity NIR detector ISA041H2

This is an example of using a light source of 1550 nm andobserving the light from the exit side of Silicon waveguide.
At the same time, by using infrared halogen coaxial
epi-illumination, microscopic image of exit side of silicon
waveguide is observed.

ISA041H2 and ISA041VH have the same pixel pitch, so the resolution is the same. On the other hand, since total number of pixels is diﬀerent, eﬀective
element size will change. ISA041H2 is suitable for use in combination with Synosʼ NFP measurement optics and standard type FFP measurement optics
M-Scope type F. On the other hand, when used in combination with IR high-resolution FFP measurement optics M-Scope type FHR and the wide area FFP
measurement optics M-Scope type FW, ISA041VH is indispensable. Please contact us for the details of the detector selection.
