Optical design for the development of optical products and systems

Nuestro trabajo siempre comienza con el diseño de concepto: este es un punto fundamental para lograr un sistema óptico funcional. El proceso de diseño óptico implica la elaboración de un diseño a medida basado en los requisitos específicos de cada cliente, pero eso no es suficiente: cada solución óptica debe ofrecer algo más que cumplir con las especificaciones, debe de ser un diseño óptico viable, fabricable. En ASE Optics somos expertos también en fabricación óptica y sistemas ópticos y eso nos permite ofrecer diseños aptos y adecuados para una fase posterior de desarrollo y fabricación.

Capabilities and experience

We have extensive experience in physical optics, geometrical optics, photonics, optical physics, opto-mechanics and opto-electronics. We design complex optical systems and precision optics for different applications. At ASE Optics Europe we use the most advanced tools and software, such as Code V®, ZEMAX® or Matlab®, to establish the optical models, to perform the simulations of optical systems operation and to be able to take into account all the parameters that affect the system: light propagation from a source or scene, the sensor… Through calculation, simulation and the application of optimization algorithms, we shape the optical components to achieve the best optical function, taking into account environmental factors such as thermalization, sealing, pressure or vibration. This involves varying optical surfaces, relative distances, materials, optical coatings, etc., always keeping in mind that the ultimate goal is to achieve a manufacturable and efficient design. ASE Optics Europe is at the frontier of the state of the art in the application of advances in optical surfaces, from refraction and reflection, to diffractive optics and free-form optics.

Custom lens design

One of our specialties is custom lens design. We provide precise, high quality designs so that all your lenses meet the characteristics required by each application, including aspects such as costs and manufacturing limits. If you need to optimize your lens design for manufacturing, and make your product more efficient in the mass production phase, our team of experts will offer you the complete solution: optical design, material selection, tolerance analysis and optical performance… you will get an optical design with clear specifications, which will fit all requirements, technical and quality.

Each of the parameters are studied with the utmost accuracy and precision by our team of optical engineers, using all available techniques such as ray tracing to simulate the performance of each lens.

Some examples of our experience in custom optical lens design are:

Imaging lenses and customized objectives

Optical design of lenses for integration into imaging systems. They are key components for focusing the image of an object and allow an object to be viewed in various ways, depending on specific needs. Depending on the design of these lenses, we correct perspective errors, provide adjustable magnification or modify the field of view or focal length of the system.

We design custom lenses for both visible spectrum (VIS) and infrared wavelength systems (IR, LWIR, MWIR, SWIR).

Lenses for laser collimation

Laser collimating lenses are used to convert diverging light beams into parallel beams. At ASE Optics we design custom lenses and lens systems for laser collimation for different applications and spectral ranges, from ultraviolet (UV) to infrared (IR). We have experience designing aspheric and achromatic lenses, compatible with various light sources, such as laser diodes.

Usually, laser collimating lens systems are composed of several optical elements, at ASE Optics we take into account all the necessary requirements to design the most suitable lenses: materials, entrance pupil diameter, wavelength, focal length, focal length and field of view.

Development of integrated optical systems

Making the leap from drawings to assembly to obtain an optical system that works in its actual application is one of the biggest challenges in the optical system development process. As they say in the industry: “optics don’t float”. ASE Optics has the experience and resources to successfully carry out precision optical system assembly, prototype production and short series system manufacturing.

As they say in the industry: “optics don’t float”.

In the assembly process, the optical elements must always be within the specified tolerances, and positioned efficiently, in order to last during use.

Assembly procedures begin to be defined during the early stages of the optical design process. Each optical system is unique, but at the same time, at ASE Optics we take full advantage of our experience in optical system assembly to replicate and apply proven techniques, within the uniqueness of each system, while applying the right amount of precision required in each case.

Our process can achieve accuracies of less than 5 microns of off-center and air gaps, and <3 arcmin of tilt… but only when necessary.

Integration of optical systems: optics, optomechanics, and optoelectronics.

ASE Optics Europe manufactures and assembles custom precision optical systems and equipment, following our certified quality process.

Through the use of professional design software such as SolidWorks, we turn optical system designs into real products. In addition, our mechanical engineers design prototypes and systems that are easy to manufacture and assemble, while still achieving the highest precision. This is thanks to its extensive experience in the design of optomechanical systems, lens frames, accessories and mounting hardware.

During the whole process, we take into account the specific specifications for each optical system, such as thermal constraints, environmental conditions, vibration, mechanical stress, pressure…

The entire team works day in and day out with the manufacturing technicians to ensure that every design is feasible and easily manufactured and assembled. Thanks to this close collaboration, we can quickly address any problems or issues that arise during the prototyping or mass production phase.
