Improving slit lamp imaging quality doesn’t always require changing the camera, sensor, or optical system.

A highly effective upgrade comes from something much simpler: background illumination.

� Why Background Illumination Works

Slit lamp imaging often suffers from:

• High contrast between illuminated and non-illuminated areas
• Shadow regions around lids and lashes
• Insufficient diffuse light for full-field visualization
• Reduced color accuracy and anterior segment detail

Adding a background lamp introduces uniform diffuse illumination, which technically results in:

• Higher signal-to-noise ratio (SNR)

More ambient photons reaching the camera sensor reduce noise in darker regions.

• Better contrast uniformity

The camera captures both illuminated and peripheral structures more evenly.

• Enhanced dynamic range utilization

Balanced lighting prevents highlights from clipping and shadows from crushing.

• Improved color reproduction

The diffuse backlight stabilizes white balance and reduces color cast.

� Clinical Advantages

With background illumination, practitioners can expect:

• Clearer corneal surface imaging
• Better visualization of lens opacities
• Sharper images for documentation and telemedicine
• More consistent imaging results across different operators
• Improved teaching-quality videos and photos

� Ray Vision Upgrade Offer

For a limited time, every Ray Vision slit lamp purchase includes a FREE background illumination module, enabling an immediate up to 50% performance improvement without modifying the optics or camera.

If you rely on slit lamp photography or anterior segment imaging, this enhancement provides one of the highest ROI upgrades you can implement.
