35mm F/4.8 Optical Recording Lens for Display Imaging

The PDN-35 CRT Recording Lens is a specialized optical lens designed for capturing images from CRT displays and recording them onto 35mm film. Originally developed for medical diagnostic systems, this precision optical lens provides reliable imaging performance for display capture and short-distance optical recording applications.

Universe Optics currently has a limited inventory of PDN-35 lenses available, making this a rare opportunity for engineers and system designers seeking specialized optical components for legacy systems, instrumentation, or experimental imaging setups.

Price: $27.50 each.

Key Features of the PDN-35 Lens

Short Object-to-Image Distance The PDN-35 lens is designed for applications where the object and image planes must be positioned close together. This makes it suitable for compact recording systems and display capture configurations.

Flat Image Plane The lens maintains a flat image plane across the entire 35mm frame, ensuring consistent focus and accurate image reproduction.

35mm Film Coverage The optical design fully covers 35mm film format, allowing precise recording of display images without edge distortion or loss of clarity.

Designed for Display Capture The PDN-35 lens was originally engineered for CRT display recording systems used in medical imaging equipment, making it well suited for capturing screen-based images.

PDN-35 Technical Overview

  • Lens Type: CRT Recording Lens
  • Focal Length: Designed for 35mm recording systems
  • Aperture: F/4.8
  • Format Coverage: 35mm film
  • Image Plane: Flat-field design
  • Object Distance: Optimized for short object-to-image distance imaging

This optical configuration allows the lens to accurately reproduce display images across the full recording surface.

Original Application: Medical CRT Recording Systems

Before digital storage systems became common, many medical imaging devices used CRT monitors to display diagnostic images. To preserve patient records, those images were recorded onto 35mm film using specialized optical recording systems.

The PDN-35 lens was designed specifically for this environment, providing the optical characteristics necessary to capture CRT screen images with reliable accuracy.

While modern imaging technology has evolved, the lens design still provides useful capabilities for certain optical systems.

 

Potential Applications Today

Although CRT recording is less common today, lenses with these characteristics can still be useful in specialized optical systems.

Possible applications include:

  • Display imaging and screen capture systems
  • Optical relay imaging systems
  • Laboratory instrumentation imaging
  • Engineering prototypes and experimental imaging setups
  • Diagnostic instrumentation imaging
  • Specialty optical recording systems

Engineers designing custom imaging systems sometimes require optical components with short working distances and flat image planes, making lenses like the PDN-35 useful in certain configurations.

Limited Inventory Available

Universe Optics currently has a limited number of the PDN-35 CRT Recording Lens available from existing inventory available at $27.50 per unit.

Because this lens was originally produced for a specific application and is no longer in production, inventory is limited.
