Cassette DSLR Film Scanning Base + Diffuser Even Illumination & Flatness

Film scanning base + diffuser built for even light, stability, and repeatable results.

The Cassette Base + Diffuser is the foundation of a modular DSLR film scanning setup. It provides consistent illumination across 35mm, medium format, and 4×5 workflows—so your scans stay clean from edge to edge.

If you’re building a camera scanning setup, this solves one of the biggest issues: uneven light. The integrated diffuser smooths output from most LED light pads, reducing hot spots and keeping exposure consistent frame to frame.

Why We Built This

Good film scans start with even light and a stable base.

Most DIY setups struggle with hot spots, uneven illumination, or shifting holders. High-end systems solve this—but usually with added cost and complexity.

This setup keeps things simple: even light, stable positioning, and repeatable results.
