Optika B292LD1.50 Metallurgical Fluorescence Binocular

Description

Detect structural micro-cracks in aerospace alloys using the Optika B-292LD1.50 Metallurgical Microscope. Built for dual-mode reflected light materials science, its epi-illumination block houses both a 3.5W white LED for standard metallurgical brightfield and a 3.5W Blue LED unit with a Blue excitation filter set for fluorescent penetrant dye tracking. Operating on an infinity-corrected IOS optical system, it delivers 50x, 100x, 200x, and 500x magnification via four Long Working Distance (LWD) IOS W-PLAN MET plan-achromatic objectives: 5x, 10x, 20x, and 50x.

The 30-degree inclined binocular viewing head rotates 360 degrees, fitted with paired extra-widefield high-eyepoint WF 10x/20 mm eyepieces across an adjustable interpupillary span. The double-layer mechanical stage measures 150 x 139 mm with an active cross-travel span of 75 x 33 mm via low-drop right-hand coaxial controls. Coaxial coarse and fine focus knobs feature calibrated 2-micron fine division markings, supported by a 7.2 kg cast-metal frame (235 x 340 x 410 mm) operating on universal 100-240V AC power with an integrated manual brightness scroll wheel on the base.

Key Features of Optika B-292LD1.50 Metallurgical Microscope

An industrial metallurgical and fluorescence binocular microscope featuring integrated Blue LED excitation and reflected brightfield lighting. Combines four IOS W-PLAN MET LWD objectives with dual 3.5W white and blue LEDs, a 150 x 139 mm mechanical stage, and 2-micron focus mechanics.

• 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
• Binocular viewing head inclined at 30 degrees with 360-degree rotation for shared use
• 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 deliver clear, flat-field edge resolution
• Solid 7.2 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-292LD1.50 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 & Binocular Viewing Comfort

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. Viewing through dual high-eyepoint 20 mm eyepieces ensures relaxed, fatigue-free observation during repetitive manufacturing quality audits. The quadruple revolving nosepiece operating on precision ball bearings features positive click-stops for exact lens centering.

• 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
• Low-position coaxial XY controls reduce wrist fatigue during high-volume sample rounds
