IR Illumination

The infrared microscope illumination excels at observation of healthy cells deep within a thick specimen.

see also our IR-Camera

Near infrared light from a light emitting diode (LED) is coupled into the transmitting light path of the microscope and illuminates a specimen of some 100 μm thickness. Images of thick specimens like brain slices can be video captured. The external trigger enables the integration of the IR Illumination into our Imaging System.

specifications

• IR semiconductor light source, wavelength 760 nm, 40 mW min.
• coupled into the transmitted light condenser beam
• coupling via dichroic mirror (DCSP 700)
• intensity control of the IR-LED via potentiometer
• external gating through TTL-pulse

IR CCD Camera VX 55

The VX55 is a monochrome video camera with a "lens-on-chip" CCD sensor to deliver increased sensitivity. The VX55 delivers the full PAL resolution of 740x575 pixels. Our camera allows to adjust offset and gain to improve the object contrast significantly. The IR CCD camera can be used as a standalone camera in combination with IR-filters or with our IR-illumination system.
_{Note: The microscope requires DIC optics.}
