Optika B293LD1.50 Metallurgical Fluorescence Trinocular

Description

Detect semiconductor micro-cracks and material fatigue boundaries under Blue LED excitation using the Optika B-293LD1.50 Metallurgical Microscope. Built for dual-mode industrial analysis, its reflected light housing incorporates both a 3.5W white LED for standard metallurgical brightfield and a 3.5W Blue LED fluorescence unit with a Blue excitation filter block. Operating on an infinity-corrected IOS optical system, it delivers 50x, 100x, 200x, and 500x magnification through four Long Working Distance (LWD) IOS W-PLAN MET objectives: 5x, 10x, 20x, and 50x.

The 30-degree inclined trinocular head features widefield high-eyepoint WF 10x/20 mm eyepieces and an overhead vertical photo port with a selectable 100:0 visual / 0:100 camera beam splitter. The double-layer mechanical stage measures 150 x 139 mm with an active cross-travel span of 75 x 33 mm, supported by a 7.8 kg cast-metal frame (235 x 340 x 430 mm). Coaxial coarse and fine focus knobs feature calibrated 2-micron fine division markings, operating on universal 100-240V AC power with an integrated manual brightness dimmer scroll wheel on the base.

Key Features of Optika B-293LD1.50 Metallurgical Microscope

An industrial metallurgical and fluorescence trinocular microscope featuring integrated Blue LED excitation and reflected brightfield lighting. Combines four IOS W-PLAN MET LWD objectives with dual 3.5W white/blue LEDs, a 150 x 139 mm mechanical stage, and a 100:0 / 0:100 camera port.

• Dual-purpose reflected system: 3.5W white LED for metallography plus 3.5W Blue LED fluorescence
• IOS W-PLAN MET LWD infinity objectives: 5x, 10x, 20x, and 50x for opaque surfaces
• Integrated Blue filter excitation block reveals fluorescent penetrant dye indications in micro-cracks
• Dedicated vertical photo port tower with selectable 100:0 / 0:100 optical beam splitter
• Double-layer 150 x 139 mm mechanical stage with 75 x 33 mm coaxial XY drive
• Coaxial coarse and fine focus drive with calibrated 2-micrometer (0.002 mm) graduations
• Widefield high-eyepoint WF 10x/20 mm eyepieces on a 30-degree inclined trinocular head
• Solid 7.8 kg structural metal housing isolates delicate polished surfaces from vibration

Dual White/Blue LED Reflected Lighting & Crack Profiling

Inspecting structural aerospace alloys and semiconductor packages often requires checking polished metal grains under white light, then switching to fluorescent dye penetrants to spot hairline cracks. The B-293LD1.50 handles both without swapping illuminators: use white light for grain boundary metallography, then switch to Blue LED excitation to make fluorescent penetrant dyes glow brightly inside stress fractures. Long working distances on the MET objectives provide safe clearance over irregular specimens.

Mechanical Stage Translation & Trinocular Video Output

The 150 x 139 mm mechanical stage provides smooth 75 x 33 mm coordinate translation via right-hand drop-down stalks, letting technicians scan metallurgical pucks systematically without touching specimen surfaces. Engaging the vertical photo port slider directs 100% of the light signal to digital C-mount cameras, letting failure analysis engineers stream high-resolution inspection footage straight to customer reports while actively viewing through the oculars.

• Dual white and blue LED emitters allow immediate toggling between brightfield and dye testing
• Long working distance MET optics provide safe clearance over unmounted polished alloys
• Selectable beam splitter allows 100% light transfer to digital cameras for low-noise capture
