Variable Optical Imaging System: The First of the Four Great Inventions in Lighting Optics

This article introduces the first of the Four Great Inventions in Lighting Optics: Variable Optical Imaging System.

In the lighting industry, a segment of clients specializing in R&D and production of LED pattern projection cut-off lighting products faces prevalent challenges. According to incomplete statistics, over 60% of such clients report the following pain points:

· A vast array of product lines coupled with diverse imaging lens specifications, leading to difficulties in lens selection;

· Uncertainty in inventory management for production needs, resulting in heavy stock pressure;

· Inability to meet the diverse demands of varied user groups.

To address these industry-wide challenges, TOPLITE has developed the Variable Optical Imaging System, which effectively resolves the aforementioned issues.

What is the Variable Optical Imaging System?

The Variable Optical Imaging System stands as one of the four groundbreaking inventions by TOPLITE in the field of illumination optics. Within its product portfolio, it is referred to as the IMM lens range, comprising a series of cemented lenses with diameters ranging from over 200mm to 22mm and even smaller, covering numerous intermediate sizes.

All lenses undergo high-precision machining, high-precision cementing, high-quality coating, and edge blackening for stray light elimination, thereby maximizing imaging quality and minimizing stray light interference.

How to Utilize the IMM Lens Range?

Within the IMM lens range, single or multiple cemented lenses of any size can be freely and repeatedly configured into lens combinations of varying specifications. For reference, please refer to the following optical paths:

Any lens combination can function as an imaging lens with linear zoom capability, boasting exceptional imaging quality and a smooth zoom process.

Key Features of the IMM Lens Range

As noted, the IMM lens range includes cemented lenses of multiple sizes. Through rational combination of different lenses within the range, users can:

· Achieve an almost infinite number of imaging lenses with distinct performance metrics and specifications;

· Alleviate the complexity of lens application;

· Significantly reduce lens inventory holdings (based on test combinations, only relevant lenses within the range need to be stocked);

· Expand product lines to the greatest extent possible (with multiple available combination angles);

· Cater to the needs of lighting products spanning high to low power, and large to small sizes.

Imaging Performance of the IMM Lens Range

· Uniform light spots with no chromatic aberration;

· No blue or yellow edge artifacts;

· Support for ultra-high pattern resolution, with a maximum distinguishable pixel unit of 2 microns, enabling the use of high-definition Gobo sheets in lighting fixtures for sharp, clear projected images;

· Low distortion.

Available Models of the IMM Lens Range

The IMM lens range is categorized by aperture/gobo size into IMM80, IMM60, IMM50, IMM40, IMM32, IMM25, and IMM16, where the numerical values denote the diameter of aperture or pattern content. Each model encompasses multiple angles (both fixed-focus and variable-focus) for selection. For instance, if a 25mm-diameter pattern sheet is required to develop a zoom projection luminaire with a 16° to 28° zoom range, we can rapidly configure the optical path from our existing database.

Owing to the feasibility and convenience of free lens combination, users may even randomly select lenses from the range for experimental assembly to explore more applications and innovations—an approach we actively advocate.

Compatible Light Sources for the IMM Lens Range

In terms of application, it is generally divided into pattern projection and light spot (cut-off light) projection. Typically, the smaller the light-emitting area of the source, the clearer and more uniform the pattern projection. The IMM lens range is generally compatible with various LED light sources. We will swiftly adapt and deliver a suitable condensing system in accordance with clients' light source specifications and requirements.

Additionally, the IMM lens range supports multi-color LED light sources. Leveraging another of our inventions in illumination optics—the multi-color LED mixing system—full-color patterns projection and light spots can be achieved with uniform color mixing and no impure hues.

Conclusion

The variable-focus optical imaging system (IMM lens range) features a groundbreaking design philosophy, eliminating the hassle for users of searching for lenses compatible with different luminaires. With the IMM lens range, you can obtain any pattern projection lens you require. We encourage you to contact us promptly at: +86-020-82161267   /   led3d@led3d.com
