Jelight Blak-Ray® B-100YP

is a 100 W high-intensity inspection lamp designed for semiconductor wafer inspection and fine surface particle detection. Its yellow optical filter provides high-contrast illumination for identifying small particles and surface contamination, while its heat-resistant Cool-Touch™ plastic housing allows more comfortable handling during extended inspection work.

Applications

Semiconductor Wafer Inspection

Provides high-contrast illumination for inspecting semiconductor wafer surfaces during fabrication and quality control. The yellow filter blocks wavelengths below 500 nm, reducing illumination in the spectral region where many photoresists absorb light.

Fine Surface Particle Detection

Supports visual identification of fine particles and surface contamination on precision components. Under suitable inspection conditions, the high-intensity illumination can make particles as small as approximately 10 µm visible.

Features

• High-intensity yellow-filtered illumination enhances the visibility of fine particles and surface contamination.
• Yellow optical filter blocks wavelengths below 500 nm while transmitting prominent mercury emission lines at 543, 574, and 576 nm.
• Heat-resistant Cool-Touch™ plastic housing reduces external housing temperatures compared with aluminum lamp-head designs.
• Detachable lamp head supports handheld operation or hands-free positioning on the transformer base.
• Lamp head rotates 360° when mounted on the transformer base for adjustable inspection positioning.

Frequently Asked Questions

What is the difference between the B-100YP and B-100Y?

Both models provide high-contrast, yellow-filtered illumination for semiconductor wafer inspection and fine particle detection. The B-100YP features a heat-resistant Cool-Touch™ plastic housing designed for more comfortable handling during extended use, while the B-100Y uses a powder-coated aluminum housing that becomes hot during operation.

How does the B-100YP yellow filter affect its inspection capabilities?

The yellow filter blocks wavelengths below 500 nm while transmitting prominent mercury emission lines at 543, 574, and 576 nm. This filtered output provides high contrast for semiconductor wafer inspection and fine surface particle detection. Unlike conventional 365 nm UV-A lamps, the B-100YP is not intended for standard longwave ultraviolet fluorescence inspection.

How long does the B-100YP take to warm up and restart?

The lamp starts immediately when cool but requires approximately five minutes to reach full brightness. After shutdown, the mercury-vapor bulb typically requires four to eight minutes to cool before restarting.

What safety precautions should be followed when operating or servicing the B-100YP?

Although the Cool-Touch™ housing reduces external temperatures, the internal bulb becomes extremely hot during operation. Avoid looking directly into the light source and wear appropriate eye protection. Disconnect power and allow the lamp to cool completely before servicing. Replace cracked or damaged filter glass promptly, and follow applicable procedures for handling and disposing of mercury-containing bulbs.
