3D chip-on-tip endoscope 

This 3D chip-on-tip endoscope design is suitable for robotic surgery applications where high resolution 3D stereoscopic imaging is required. The hermetically sealed design assures functionality through repeat autoclave cycles. High NA fiber optics are utilized to provide broad illumination across the entire field of view.


Compact microscope objective

This 0.25 numerical aperture, finite conjugate microscope objective provides 5.8 x magnification within a total optical path of 40 mm. The lens is suitable for both medical and life sciences applications requiring a high performing, compact magnification.

Fresnel lens array

The customer's goal was to develop a Fresnel Lens Array for a sensing application. Gray Optics worked with the client to define the product specifications, identified manufacture methods, identified potential vendors, and developed a detailed design. A Fresnel Lens Array was designed in Zemax mixed sequential and non-sequential mode. The design was iterated with input from the client until the desired performance was obtained. 


Scanning imaging system

The client hired Gray Optics to develop an optical design for a scanning laser microscope. To contain development costs, off-the-shelf lenses were identified and integrated into the system.  The design task included laser scanning and detection optics for a multi-channel PMT system. The imaging performance was characterized and the design was transferred to SOLIDWORKS for mechanical integration.

Eyepiece lens design

The client had developed and launched a novel optical product using an off-the-shelf eyepiece lens for capturing digital microscopy images. Improved performance was desired beyond what the product currently was capable of. Gray Optics was hired to reverse engineer the current optical design, and recommend options for improved performance.  An eyepiece lens design was developed based off of high-level parameters. Analysis showed a close match from the model to actual performance. Recommendations were made for redesign to meet the new requirements. 


Multi-pass cell

The client was developing a multi-pass cell for non-linear gas-phase spectroscopy. Gray Optics was hired to develop the optical design in Zemax and confirm proper performance of the cell. A model was developed in Zemax non-sequential mode, showing multiple mirror reflections. The model was used to specify the optical components and determine the necessary alignment degrees of freedom.

Reduced height microscope design

The customers's existing product design was developed using conventional microscope components. The total height was too tall and the image size was too small. Gray Optics developed a novel architecture using off the shelf components. The height was reduced by more than 2x and the field of view was increased by 30%. Using agile development techniques, more than 4 hardware iterations were completed in 3 months. The design was transferred and the client has begun building pre-production prototypes.
