ECOPTIK supports customization of integrated lenses：

Single piece design: Directly processing the curvature of the lens (such as plano convex and plano concave) on the slope or plane of the wedge-shaped window, forming a "wedge-shaped lens" integrated structure.

Component based design: bonding wedge-shaped mirrors with plano convex/plano concave lenses to reduce aberrations through optical correction while reducing weight.

Functional reuse design: The combination of lens and window not only meets the requirements of infrared transmission packaging, but also provides focusing function, simplifying the process.

We can also offer kinds of half sphere lens for sale. If you are interested, please contact us.

Optical right angle prism is another key optical product in our product portfolio that can work in conjunction with variable ND filter systems to achieve stable light direction adjustment and output control. If you need further product specifications, pricing information or customized processing solutions, please contact our professional technical team via the contact information shown on our website.

Planar convex lens is another supporting optical component that can be matched with variable ND filter systems. It can converge the incident parallel light to a focal plane after the light passes through the variable ND filter, which is an important structural unit to ensure the normal light output of the combined optical path. You can choose matching planar convex lens products of different specifications according to your actual optical path design, and our technical support team can provide you with corresponding parameter consultation and model selection suggestions.

Features of Neutral Density Filter

ECOPTIK makes fixed OD value absorptive neutral density filter by depositing Inconel film on a clear cubstrate. The advantage of the optical power density filter is in the broader band and lower ripple than that of absorptive nd filter. The coated wavelengthcan be extended to 200nm to 1100nm or more. The disadvantage is that there is some reflective light on the optical filter glass. The OD value can vary from 0.1 to 0.5. The OD value is controlled by coating inconel thin film thickness. Regular thickn thickness of the NDF is 1.1mm or 0.55mm.

This kind of optical power laser density filters can be used for video, waterfalls, ophthalmology and landscape photography.

Neutral Density Filter Types

1. Absorption type nd filter od

Working principle: Made of glass or optical plastic containing uniformly suspended carbon particles or metal particles. These particles uniformly reduce light intensity by absorbing light energy and converting it into thermal energy.

Features:

Advantages: Low cost, insensitive to incident angle, and less prone to stray light.

Disadvantages: Under high-power laser, it may rupture or produce thermal lens effect due to heat absorption, and its neutrality may not be as good as that of reflective type.

2. Reflective ND filter

Working principle: Coat a metal film with neutral reflective properties (such as chromium, nickel chromium alloy, inconel) on a glass substrate. Reduce light by reflecting (rather than absorbing) a portion of the light.

Features:

Advantages: It usually has better neutrality, high temperature resistance, and high power.

Disadvantages: High cost, reflected light may form ghosting or stray light, affecting system performance.

3. Reflection/absorption hybrid type

Combining the advantages of both, it is commonly used in high-end photography ND mirrors to minimize ghosting caused by reflection while ensuring neutrality.

4. Variable ND filter

Working principle: Composed of two linear polarizing plates. When a polarizing film is rotated, the angle between its polarization direction and the other film changes, thereby continuously changing the transmittance.

Features:

Advantages: One filter covers multiple OD values, which is very convenient.

Disadvantage: It is not truly "neutral" and is sensitive to polarized light, which may result in uneven sky color or "cross shaped" dark corners. The imaging quality is usually inferior to fixed ND mirrors.
