Overview

The Heliopan 5695 Infrared Filter is a moderate-strength infrared pass filter engineered for both dedicated near-IR digital sensors and specialty analog film emulsions. It creates a gateway to an invisible spectrum by blocking visible wavelengths up to 695nm, matching the optical characteristics of the classic 89B filter standard. Unlike deeper IR filters that seal off the visible spectrum entirely, this glass allows a controlled portion of deep visible light to blend with near-infrared radiation. This specific transmission profile yields slightly softer monochrome contrast than pitch-black red filters, making it perfect for color false-color infrared manipulation and smooth, dream-like black-and-white tonal grading.

Features

• Hybrid Light Transmission: Blocks visible rays up to 695nm to mix invisible near-IR wavelengths with deep-red spectrums for versatile color and monochrome work.
• Dual-Sided Single Coating: Treated on both surfaces to raise overall transmission, lock down stray reflection flare, and secure pristine micro-contrast.
• Schott Optical Core: Uses premium ground and polished Schott glass substrates to preserve optimal frame-to-frame pixel clarity.
• Low-Profile Knurled Ring: Features a slim, wide-angle-safe brass frame detailed with deep knurling and a friction-reducing coating for comfortable mounting.
• Manual Control Optimized: Bypasses automated camera sensors to give creators absolute control over exposure and manual infrared focal adjustments.
• Front Pass-Through Threads: Features matching front threading to stack alternative accessories or mount standard caps without binding.
