What Does a Condenser Lens Do?
A condenser lens gathers light from a source and focuses it onto a target area, improving brightness and clarity. Key functions include:
- Increasing Illumination: Directing more light to the desired spot.
- Enhancing Image Contrast: Essential for microscopy and medical imaging.
- Reducing Light Loss: Improving system efficiency.
Condenser Lens in Microscopes
In microscopes, a condenser lens focuses light onto the specimen for clear, high-contrast imaging. Features include:
- Adjustable aperture to control brightness and depth of field.
- High numerical aperture (NA) for better resolution.
- Abbe condensers and aspheric designs for optimal performance.
Condensing Lens in Ophthalmology
Ophthalmic condensing lenses are used in retinal examination and laser treatment. They help eye specialists get a clear view of the retina, enabling accurate diagnosis and procedures. Common types include:
- 20D Condensing Lens: A standard lens for indirect ophthalmoscopy, providing a wide field of view and high magnification.
- Aspheric Lenses: Minimize distortion for sharper imaging.
- Coated Lenses: Reduce reflections and enhance light transmission.
20D Condensing Lens – Features & Benefits
A 20D condensing lens is widely used in ophthalmology for indirect ophthalmoscopy.
- Magnification: ~3x image magnification for detailed retinal examination.
- Field of View: ~46° static, ~60° dynamic.
- High Transmission: Anti-reflective coatings for better clarity.
- Durable Design: Precision-polished optics with lightweight housing.
