Infrared imaging slit lamp

BL-99G

Five-step Galilean microscopy with a built-in infrared imaging system for direct examination and infrared documentation from one platform.

Extend the view beyond visible light.

The BL-99G combines direct binocular examination with a built-in infrared imaging path. Five-step Galilean optics remain at the center of the instrument, while the dedicated imaging assembly gives the practice a second way to document the examination without moving to a separate platform.

Five magnifications around one optical center

The microscope advances through 6×, 10×, 16×, 25×, and 40× magnification. Lower power maintains orientation across the examination field, while the higher settings bring smaller structures into closer view.

The 12.5× eyepieces include 50–82 mm interpupillary adjustment and +7 D to −7 D diopter correction, allowing the binocular view to be set for the individual examiner.

Move from a narrow section to a broad field

The LED slit adjusts continuously from 0 to 14 mm in width and from 1 to 14 mm in height. The illumination arm rotates through 180 degrees, with five inclination positions for changing the relationship between the beam and microscope.

Selectable spot diameters support concentrated or wider illumination while the main controls remain accessible from the examination position.

Change the viewing condition at the instrument

Heat-absorption, neutral-density, red-free, cobalt-blue, and built-in yellow filters are integrated with the illumination system.

Yellow barrier
The yellow barrier works with cobalt-blue illumination to increase the visible contrast of fluorescein staining.
Cobalt blue
Cobalt-blue illumination provides the excitation light used for fluorescein-assisted surface observation.
Neutral density
Neutral-density filtration lowers beam intensity without introducing a strong color shift into the visible field.
Red-free
Red-free viewing separates vascular detail from surrounding tissue through increased tonal contrast.

The filter selector keeps these options within the normal sequence of alignment, illumination, and observation.

A stable base for an expanded imaging assembly

The BL-99G provides 110 mm of side-to-side base movement, 90 mm of fore-and-aft travel, and 30 mm of vertical adjustment. The chin rest moves through an additional 80 mm for patient alignment.

The joystick and graduated controls support fine positioning beneath the added imaging hardware, keeping the microscope, illumination arm, and camera assembly together as one working instrument.

Infrared imaging built into the examination path

A dedicated infrared imaging system is mounted directly to the slit lamp microscope. The integrated arrangement keeps infrared capture aligned with the examination platform and available alongside direct binocular observation.

Sensor resolution, infrared wavelength, capture formats, and software configuration are not specified in the supplied product information and can be confirmed during product consultation.
