Newly launched RGBA achromatic fiber collimators

New Product Launch | UltraOpto RGBA Achromatic Fiber Collimators: A New Choice for Precise Multi-band Optical Path Control

Addressing the core pain points of red, green, blue, and ultraviolet (RGBA) multi-band light collimation, UltraOpto has newly launched RGBA achromatic fiber collimators. With professional achromatic optical design, it breaks through the limitations of traditional single-wavelength collimators, precisely compensating for multi-band chromatic and spherical aberrations. It achieves accurate collimation and efficient coupling of the entire 300-700nm wavelength range, featuring high pointing stability and low loss. It provides an integrated multi-band optical path solution for fields such as laser display, machine vision, and optical communication.

Core hard-sell points, empowering multi-band optical path upgrades 

Full-band RGBA achromatic aberration correction, no frequent adjustments required: Utilizing an aspheric lens group combined with low-dispersion optical glass, it precisely compensates for the material dispersion and optical path aberration of the red, green, blue, and ultraviolet bands. The focal length remains constant within the 300-700nm range, eliminating the need for separate collimators for different bands or frequent focal length adjustments. This significantly simplifies the optical path design, enhances system integration efficiency, and ensures that the collimated multi-band beams have a round and distortion-free spot, presenting an undisturbed Gaussian beam profile. 

Bidirectional high-efficiency transmission with low loss and high coupling: 

Enhanced by vacuum ion sputtering multi-layer anti-reflection coating, the single surface transmittance is ≥ 98.5%, the total transmittance is ≥ 95%, and the reflection loss is < 0.5%, maximizing the retention of beam energy. It can be used in both directions, capable of achieving precise collimation of the light emitted from the fiber as well as efficiently coupling spatial light into the fiber. The coupling efficiency for single-mode fiber is ≥ 80%, and for multimode fiber, it is ≥ 85%, meeting the diverse requirements of optical path layout. 

High pointing stability and industrial-grade reliability and durability: 

Ultra-precise mechanical assembly process, with extremely small coaxiality error between the ceramic ferrule and the lens group, the pointing angle deviation is less than ±2μrad, and the spot displacement during 360° rotation is less than 0.01mm. There is no pointing drift under long-term operation, environmental temperature changes or slight vibrations. The lens group is stress-free fixed to the housing, with strong adhesion and wear resistance of the coating layer, and the working temperature range covers -20℃ to 70℃, with an extremely low temperature drift coefficient, which can meet the long-term continuous operation requirements of industrial equipment. 

Multi-specification compatibility and stronger customization: 

Compatible with single-mode and multi-mode optical fibers of different core diameters, with numerical aperture adaptation ranging from 0.22 to 0.5. Standard interfaces include FC/PC and FC/APC, with SMA905 interface available as an option. The ceramic ferrule concentricity is ≤ ±2μm. Conventional housing diameters are φ12mm and φ16mm, with focal lengths selectable from 10 to 20mm. It supports personalized customization of non-standard focal lengths, interface types, and fiber compatibility specifications, perfectly matching the requirements of different optical systems. 

Diverse application scenarios, covering the demands of multiple fields 

As a core component of multi-band optical systems, it is widely used in fields such as laser display and cultural tourism light shows, multi-band detection in machine vision, color optical communication and fiber sensing, bio-fluorescence imaging, semiconductor wafer inspection, and ultraviolet + visible light laser processing. It can not only help laser projection and light and shadow shows achieve higher brightness and color uniformity, but also improve the accuracy and efficiency of multi-band detection and optical communication, meeting the strict requirements of various scenarios in scientific research, industry, and consumer electronics. 

Relying on the precision manufacturing process based on ISO standards, the product features both high reliability and stability. It shows no performance degradation after cold and hot cycling and vibration tests, and can be adapted to complex industrial conditions without additional protection. It has become the preferred core component for multi-band optical path control, facilitating technological upgrades and efficiency improvements in various fields.
