Ultra-wide-angle lenses, as well as fish-eye lenses, create a sense of distortion in horizon lines and other straight lines that other lenses won’t produce.

By developing the ability to guess what focal length has been used for an image, you can further understand how lenses control depth and perspective.

How do you manage the spectral complexities needed for spatial biology analysis? Steep edges and deep blocking are your solution.

If you’re using a zoom lens, the minimum and maximum focal distance should be printed on the barrel’s zoom ring, indicating your position between these focal lengths.

Optical filter

Whether using a converging lens or diverging lens, the focal lengths represent the distance from the optical center to the image plane in the camera.

For example, if an object is 50cm away from a lens and produces an image of 100cm, the focal length of the lens will be 33.3cm.

Unless you’re using a fixed focal length prime lens, you may wish to figure out how to convert your lens’s focal length to its optical zoom.

At the same time, bear in mind that crop factor may be something to consider when working out the optical zoom capabilities of a given lens and sensor combination.

Looking to replace your CCD camera and achieve similar performance? Consider an IDEX Health & Science CMOS camera with higher resolution and throughput.

The equivalence of a 10x zoom in millimeters is dependent on the initial starting point and whether you’re using a crop or full-frame camera.

Figuring out the equivalent crop factor for different camera formats is a handy way to quickly convert the size of media you can work with.

If you’re using a prime lens, the focal length will be fixed to the lens’s native setting, with no adjustable scale to work with.

Conversely, super telephoto lenses bring the foreground and background elements together and can be used to create interesting patterns and textures.

If you don’t have the mathematical know-how or time to calculate focal length, these statistics can help you save time and cut to the information you need.

Explore a wide range of laser and LED illumination light engines to meet your application needs from Next Generation Sequencing, Cytometry, Fluorescence Microscopy, and Spectroscopy in clinical and research environments.

Finding the focal length of a specific camera lens is easy, and is typically printed directly on the barrel of the lens for ease of access.

Optical filters can be searched by individual filters and by set. You will also still have access to the e-store left navigation filtering that you are used to from the historic semrock.com to search by wavelength, filter families, fluorophore, filter type, light source, laser wavelength, edge steepness, flatness, application, and more.

Concave lenses are thicker on their edges and cause light to diverge away from the focal point while having a negative focal length.

A larger zoom lens with a coverage of 18 – 200mm would have a larger optical zoom coverage, with the equation revealing this as an 11x optical zoom.

On the other hand, convex lenses are thicker in the middle and bring light to a point to create a positive object distance and an inverted image.

Another way to calculate focal length is by using the lens equation technique, for which you’ll need to know the distance an object is away from the lens and the image distance.

The more you experiment with different focal lengths, the easier it will be to spot images taken with a longer or shorter focal length.

For example, wide-angle lenses create a sense of space and immersion, while telephoto lenses work well to flatten perspective.

It’s important to bear in mind that different brands sometimes have different crop factors for their various camera sensors.

To do so, you’ll need to factor in the minimum and maximum focal length of the lens’s zoom capabilities in this simple equation:
