Triton Blue Fresnel Lens 175mm - Glass Lens for Professional Lighting

Triton Blue Fresnel Lens 175mm - Glass Lens for Professional Lighting

The Triton Blue 175mm Fresnel lens is a high-quality optical component, specifically designed to meet the demanding needs of professional lighting in theaters, television studios, and live events. Made from high-purity glass, this lens guarantees superior light transmission and exceptional durability, withstanding the high temperatures generated by high-power lamps without warping or losing clarity over time.

Its design, based on Augustin-Jean Fresnel's principle, utilizes a series of concentric rings to achieve the optical properties of a much thicker and heavier plano-convex lens. The result is a lightweight and efficient component that produces a distinctive light beam characterized by its soft, diffused edges, allowing for seamless blending between different light sources. This quality is essential for creating immersive environments and atmospheres, eliminating harsh shadows and providing remarkably uniform field coverage. With a diameter of 175 mm, this lens is compatible with a wide range of projectors and moving heads on the market.

Main Features

• 175mm Diameter: A standard size that ensures compatibility with a wide variety of professional lighting fixtures, including theater projectors and moving head wash lights.
• High-Quality Glass Construction: Unlike plastic alternatives, glass offers superior heat resistance, impeccable optical clarity, and a long lifespan without yellowing or deteriorating.
• Classic Fresnel Design: Concentric ring technology significantly reduces weight and thickness, making it easier to handle and install without compromising the quality of the light beam.
• Superior Beam Quality: Generates a soft and homogeneous light field with blurred edges, ideal for achieving clean and professional color transitions and light blends.
• Application Versatility: Perfect as a replacement or upgrade for a wide range of equipment, from traditional profile projectors to modern moving heads.

Product benefits

• Precise Lighting Control: Allows the lighting designer to shape the light beam, adjusting the focus to smoothly transition from a concentrated beam (spot) to a wide beam (flood), adapting to each stage need.
• Maximum Luminous Efficiency: The high transparency glass ensures minimal light loss, maximizing projector performance and guaranteeing faithful and vibrant color reproduction.
• Long-lasting Investment: Its robust glass construction protects it against extreme heat from the lamps, ensuring consistent and reliable performance for years, making it an economical choice in the long run.
• Professional Lighting Quality: The soft-edged beam is the standard in theatre and television, as it provides flattering light for actors and eliminates visual distractions caused by harsh shadows.

Use cases

This Fresnel lens is the ideal choice for a multitude of professional applications:

• Theatrical Lighting: Essential for front lighting, backlighting, and creating general color washes on stage. Its soft beam allows performers to stand out without creating harsh edges.
• Television and Film Studios: Provides the main, fill or background light on film sets, ensuring uniform and natural lighting for interviews, programs and film productions.
• Professional Photography: Used in continuous light sources for portrait and product photography, where a soft and controllable light is sought that delicately models the subject.
• Live Events and Concerts: Integrated into wash-type moving heads, it is essential for creating dynamic environments, covering large surfaces with color and generating impactful visual effects.

Frequently Asked Questions

Is this lens compatible with any projector that uses 175mm lenses?
Yes, it's designed as a standard for projectors that support 175mm diameter Fresnel lenses. However, it's always recommended to check the mounting specifications and focal length required by your specific equipment to ensure a perfect fit.

What material is the lens made of?
It is made entirely of high-quality optical glass, which gives it excellent clarity and superior resistance to high temperatures compared to plastic lenses.

What is the main difference between a glass Fresnel lens and a plastic one?
The main difference is heat resistance. Glass can withstand much higher temperatures without warping or being damaged, which is crucial in projectors with powerful lamps. Furthermore, glass does not degrade or yellow over time and generally offers superior optical quality.

Can I use this lens to replace the one on a wash-type moving head?
Absolutely. It's one of its most common applications. As long as the 175mm diameter is correct for your moving head model, this lens will serve as a high-quality replacement to restore or improve your equipment's performance.
