Dimensions
*2: Depends on the slit opening. Values were measured with the slit opening listed in the table.
*3:
λ
=550 to 1100 nm
*4: Measured under constant light input conditions.
*5: When monochromatic light of the following wavelengths is input, spectral stray light is defined as the ratio of the count
measured at the input wavelength, to the count measured in a region of the input wavelength ±20 nm (C9404MC) or ±40
nm (C9405MC).
C9404MC: 300 nm, C9405MC: 800 nm
*6: This is the ratio of the transmittance measured with light passing through the following optical filters to the transmittance
measured in the blocking region.
C9404MC: WG320, C9405MC: RG850
*7: Entrance slit aperture size
*8: Numerical aperture (solid angle)
*9: USB bus power
*10: No condensation

Optical component layout
TG series mini-spectrometers use a transmission holographic
grating made of quartz and precision optical components
arranged on a rugged optical base, making it possible to
deliver high throughput and highly accurate optical charac-
teristics.

Connection example
(transmission light measurement)
Light to be measured is guided into the entrance port of TG
series through an optical fiber and the spectrum measured
with the built-in image sensor is output through the USB port
to a PC for data acquisition. There are no moving parts inside
the unit so stable measurements are obtained at all times. An
optical fiber that guides light input from external sources al-
lows a flexible measurement setup.
