Improving the transmission or sensitivity.

  • We can’t seem to find an off-the-shelf lens which matches the specifications that we’re looking for... If we could change the lens coatings, it would meet our specifications. What should we do? Kowa Optical Products Company can create the optimum coatings that fit your needs!

For the solution see the next pages!

  • Q.Is it possible to change the lens coatings?

    We would like to use your off-the-shelf lens but want to change the coatings to increase the transmission in the near-infrared wavelength range.
    Would that be feasible?

    A.Yes, it’s possible!

    Kowa has factories that are equipped with coating processing equipment.
    We can support customer requests for any specific wavelength range such as NIR and SWIR.
    Water-repellent, oil-repellent, and other unique coatings can also be applied.

CASE2

Reducing the risks of failure when using lenses
on manufacturing and inspection lines.

  • Since we are using our system in a manufacturing line, a lens without locking screws would be ideal. Is it possible to change the screws? Our system is also exposed to strong shock and vibration… If the screws fall off, we’d have to stop the entire production line to check the safety conditions and manufacturing proceasses.

  • Q.We’d like a lens that is ruggedized and has no locking screws.
    Do you have any good solutions?

    We are worried that the lens locking screws used in the adjustment of the focus and the iris might drop out of the lens due to vibration or impacts.
    If the locking screws drop out onto the manufacturing line, we’d have to stop the line.
    Don’t you have any good proposals?

    A.Yes we have!

    In addition to having the best optical designers in the industry, Kowa also employs many skilled mechanical engineers.
    By combining both optical and mechanical design expertise, Kowa has created a unique ruggedized lens that eliminates the need for locking screws and many moving parts.
    Kowa’s ruggedized lenses are especially ideal for applications in the food and pharmaceutical industries.
    Furthermore, with Kowa’s locking ring type design, the focus can be adjusted from any direction, allowing for more fine tune settings to be made even in locations and/or housings where the lens is difficult to reach.

Designing a smaller or compact lens.

  • We’re developing the hardware, but standard commercial lenses that match our requirements are too large to incorporate in the equipment... Is it possible to make the lens slightly smaller? Kowa Optical Products Company can provide custom solutions!We’re developing the hardware, but standard commercial lenses that match our requirements are too large to incorporate in the equipment... Is it possible to make the lens slightly smaller? Kowa Optical Products Company can provide custom solutions!

  • Q.Can we take an existing off-the-shelf lens and make it smaller?

    We managed to find a lens that meets our specifications, but it is unfortunately too big to fit into the equipment that we are currently developing.
    Could you make the lens smaller?

    A.Yes we can!

    By utilizing aspherical lenses, it is possible to develop and manufacture an optical system that is smaller and lighter, while still maintaining peak performance.
    The vibration and shock resistance of a lens will also improve as the size decreases.

Creating the best camera and lens combination.

  • Is it possible to customize a camera together with a lens? When we find an ideal camera, there are often no matching lenses or vice versa. We want to have the best solution without compromising the performance of either the lens or camera.

  • Q.Can we manufacture a camera and lens as one fully integrated unit?

    We are looking for a vision solution that can be used in a system with very tight size constraints.
    When we find an ideal camera, there are often no matching lenses that work well or vice versa.
    It would be great if Kowa could supply both the camera and lens with the strict requirements we have in mind.

    A.Yes, We can!

    We can design a camera and lens unit that minimizes the size and maximizes the performance.
    By developing the camera and lens as one cohesive hardware, it will be possible to reduce the size and cost without sacrificing quality.

    Creating the best camera and lens combination.
