DayOptics

Dayoptics has specially designed achromatic waveplates, containing two pieces of plates. They are similar to zero-order waveplates, except that the two plates are made from different materials, such as crystal quartz and magnesium fluoride. The bandwidth of such achromatic waveplates is very wide, meaning a nearly constant retardance over a large range of wavelength.

DayOptics offers a polarization-maintaining AOM (acousto-optic modulator) which is specially developed for the requirements of optical sensing. It has the advantages of small size, low power consumption, fast rise time, good modulation pulse shape (small overshoot), good pulse repeatability (small repetition period jitter), etc. An integrated package containing both the modulator and the driver facilitates system integration. The device features a high damage threshold and high extincition ratio, and can be widely used in various optical fiber sensing systems that require pulse modulation, such as φ-OTDR, BOTDR, and OFDR.

DayOptics produces polarizing cube beamsplitters with epoxy interface. Coatings are available for a wide range of operation wavelengths.

DayOptics has over 18 years of design and manufacturing experience, coupled with advanced metrology, to provide our customers with world-class custom optical designs. Our engineering team excels in creating various lens designs, lens assemblies, and other optical components, catering to a wide array of applications including imaging, illumination, customized optical modules, and precision optical devices for high-power laser systems. Our expertise spans the customization of optical designs for deployment across the spectrum from deep ultraviolet to far infrared.

Backed by seasoned engineers, we leverage cutting-edge tools and software, notably Zemax, for modeling and simulations, guaranteeing best performance of our optical devices.

We have several process patents, and assure you that DayOptics is committed to delivering optimal optical solutions tailored to your requirements.

Dayoptics' engineers have many years experience on fabrication on cylindrical lenses. We can produce the products with high precision and specification consistancy based on our advanced inspection instrument for the lenses. The material used from UV to IR are fused silica, BK7, CaF₂, S-TIH53 and others. The lens dimensions range from 1 mm × 1 mm to 100 mm × 100 mm.

Our electro-optic Q switches have excellent electro-optical properties, high damage threshold, high transmittance, and are easy to adjust.

Our free space isolator is composed of a birefringent crystal (or polarizer), a Faraday rotator and a half-wave plate. It is used in fiber lasers and can effectively stop back reflections.

Our Faraday rotators have aperture diameters up to 15 mm and can work with up to 100 W of optical power and >98% transmission.

DayOptics offers a wide range of laser mirrors with different substrate materials, dimensions up to 50 mm × 50 mm, high damage threshold (10 kW/cm² at 1064nm), HR or output coupler coatings for a wide range of wavelengths.

DayOptics offers various types of of optical filters for industrial measurement, environmental protection and other fields. We provide long-wave pass filters, narrow-band filters, band-pass filters, colored glass filters, etc. Size and coating requirements can be customized.

The high-power, high-speed fiber acousto-optic modulator (AOM) is one of the core components of all-fiber laser. It has the advantages of ultra-high extinction ratio, low insertion loss and fast rise time, and can select and modulate pulse lasers.

Dayoptics provides various types of optical windows, for example for projection and imaging applications, including customized versions.

Dayoptics has newly developed thin film polarizers with 45° incidence. We can assure high transmission >95% and high reflection >99%.
