Brilliant Round Diopters

Lindsey Optics Brilliant Round Drop-In Diopters increase lens magnification and allow you to capture detailed close-up images of small subjects. They offer a lightweight alternative to a dedicated macro lens while fitting directly into standard cinema matte boxes and filter holders. Designed for professional filmmaking, these diopters deliver excellent optical performance with fast installation for efficient production workflows.

Professional Close-Up Performance

Available in +1/8, +1/4, +1/2, +1, +2, and +3 strengths, these diopters let you choose the right level of magnification for every shot. The +1/8 strength provides subtle close-focus improvement, while the +3 strength delivers maximum magnification for extreme close-up work.

Multiple Professional Sizes

The Brilliant Round Drop-In Diopters are available in three industry-standard sizes to suit a wide range of professional cinema equipment. Choose from 138mm Round, 4.5-inch Round, or 152mm (6-inch) Round versions for compatibility with many matte boxes and filter systems.

Premium Optical Quality

Each Brilliant filter uses high-grade optical glass with Lindsey Optics’ durable multi-layer BROADBAND anti-reflective coating. This coating minimizes flare and light loss while preserving contrast, color saturation, and overall image quality. For even faster filter changes, the same optical glass is also available in Brilliant² 4×5.65 Tray Mount Close-Up Lenses, which mount the 138mm diopters inside professional matte box trays.
