Jelight Blak-Ray® B-100Y

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 powder-coated aluminum housing offers durable construction for laboratory and industrial inspection applications.

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.
• Scratch-resistant, powder-coated aluminum housing provides durable construction for inspection environments.
• 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-100Y and B-100YP?

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

How does the B-100Y 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-100Y is not intended for standard longwave ultraviolet fluorescence inspection.

How long does the B-100Y 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-100Y?

The aluminum lamp housing becomes hot during operation and should not be touched. Use the designated handle, 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.
