Design + Manufacture + Optic Quality


Plastic optics


  • Lightweight (half the density)
  • High resistance to mechanical shock
  • Cheap raw material
  • Cheap high-volume production
  • Cheap non-spherical features (aspheric, free-forms, diffractive)
  • Integral mounting (no thermal expansion issues)

Thermoplastic encapsulation


One of the most important features of LED and integrated circuits is encapsulation. Its main goal is to protect, favour connectivity and dissipate heat.

Currently, injection processes require a very high processing time, due mainly to the curation process of the thermosetting plastic used for encapsulation. Thus, manufacturing time, costs and precision, become the main problems of that technology for growing in an efficient and sustainable way.

Our strength is a brand new industrial injection moulding process performed with thermoplastic that improves costs, speed and performance of the process and add optical efficiency maintaining the protection against external damaging agents.

Embedded thermoplastic lens


Unlike thermoplastic encapsulation, which is used to protect the critical parts of an LED, such as the wiring, embedded thermoplastic lens process allows us to confer optical functionality to and already encapsulated commercial LED.

Currently, optical functionality is conferred to an LED by placing an external optical lens. With this technology, an injection moulding process embed a thermoplastic optics on a LED mounted on a PCB to confer optical functionality.

With this technology, LED and optics are a single component, which ensures the alignment and the robustness of the system.




Snelloptics has several measuring instruments ready to use. We also have the capability to adapt and / or develop a costum instrument adapted to your needs.



Plastic Optics

Snelloptics designs plastic optics for LED lighting. Our production process takes into account the lenses manufacturing process and its environment of use, so the final product is custom-made, having the advantage of low cost and high quality, reducing design checks and adjustments.

Snelloptics’plastic lenses are adding value to the products containing them. Lenses are quality and competitive costs created to meet the needs of our customers.


Engineering Projects

In engineering projects Snelloptics excels for our flexible working methodology, creativity in solving challenges of each project and the personalized service and proximity.

Aware of the different needs of the industrial areas, we adapt to the characteristics of the application, being sensitive to the significance of communication and of generation of wealth through value-added quality products.



Customizable photonic emitters integrated into a chip using new 3D encapsulation processes (FOTUNECHIP3D) “subsidized by the CDTI”


The general objective of this project is the design and development of a system that represents a technological leap in the measurement of the erythrocyte sedimentation rate (ESR) and coagulation, for its application in clinical diagnosis. The primary purpose of the system is to provide ESR and/or blood coagulation results in minimal time, with a minimal amount of sample, and using sustainable materials.

New head for 3D printing of metals using the DLP technique based on a stack of laser diodes

Snelloptics, through the development of this project, proposes a new head for 3D printing of metals using the DLP technique, replacing the gas laser with a stack of solid-state laser diodes and performing the optical projection of the DLP using micro-optics and lenses projection, without using the liquid crystal display (LCD), a spatial light modulator (SLM), a digital micromirror device (DMD), since these traditional optical elements will not support the energy density necessary for 3D printing of metals.

Project 2021/C005/00147324 funding by the European Union NextGenerationEU/ PRTR



The general objective of the PATRONUS project is the development of an innovative industrial process for the manufacture of sheets that generate a speckle pattern that allows the mass production of these sheets for application by speckle interferometry to the 3D reconstruction of surfaces.

Project RTC2019-007422-4 from program Retos Colaboración 2019 funding by MCIN/AEI /10.13039/501100011033


The goal of the BIOLUM project is the development of an illumination system for a device for measuring the globular sedimentation rate (VSG or ESR, Erytrocyte Sedimentation Rate in English), faster and cheaper than those available in the market currently. Being the last purpose of the system to obtain blood coagulation data.

Project funding by CDTI (Centro para el Desarrollo Tecnológico e Industrial) Exp. IDI-20200455


The objective of this project is to produce beam splitters using as base material a material resistant to industrial encapsulation, such as a polymer (PMMA, etc.). The innovative part of this project is to develop the deposition process of these particles in the “base” material to create the beam splitter.

The ECOGRAB project aims to replace a manufacturing system of diffraction gratings for encoders that intensively uses chemical products with a cleaner and more efficient manufacturing system.
An encoder is basically a displacement sensor, linear or angular, whose output consists of one or more electrical signals. All modern equipment or systems that require precise movement control require the use of encoders, one for each degree of freedom, which inform the numerical control and modern regulators about the position, speed and acceleration of the moving parts. The examples are countless: machine tools, robotics, automated industrial production processes, industrial metrology, microfabrication techniques, etc.
