You usually get a wider field of view with an 8-power binocular than you do with the same model in 10 power. A wider field of view makes it easier to spot a songbird among the branches (or a seabird on the waves. This is especially important in visually complex situations such as forest birding.

Here is why a 32mm binocular is smaller, lighter weight, and less expensive than a 42mm. And why for most people of an (ahem) mature age, it is just as bright as a binocular with larger objective lenses. As a bonus, an strange as it may seem, the 32mm binocular usually has a wider field of view than the 42mm of the same magnification.

Hands-on Review ~ Kowa's new high-end spotting scope embodies the fluorite crystal objective lens and the fine engineeering that put Kowa Prominar scopes in the top tier of birding optics. With a 99mm objective lens, this is the biggest Kowa spotting scope. See how we like it compared to the 95mm Swarovski ATX scope. (2021)

Michael and Diane Porter are avid birdwatchers who have been reviewing binoculars and spotting scopes for over 20 years. They've surveyed hundreds of binoculars and scopes, testing them for optical qualities and noting the fit-and-feel characteristics of each instrument.

This article discusses why most birders choose angled scopes rather than straight models. How it affects the steadiness of the image. Why it's easier to share the view. How it helps you look up or down.

Hands-on Review ~ The Zeiss Gavia scope bears comparison to the Vortex Razor HD, both of which became availble around 2017. Both have 85mm objective lenses. Both focus using a textured band around the middle of the scope. Both cost in the $1500-$2000 range. This article compares their design and quality.

Asphericlens glasses

Our aspheric lenses are inspected and optically tested to ensure complete customer satisfaction. Visual cosmetic inspection for scratch/dig is performed on 100% of all lenses per MIL-PRF-13830B. Most lenses are guaranteed to pass 40/20 scratch/dig, but other inspection criteria, such as 60/40 or 20/10, can be provided upon request.

Traditionally, aspheric lenses have been produced by complex grinding, CNC machining or diamond turning, but with advances in glass molding technology, precision molded glass aspheric lenses can now be produced at low cost while maintaining a high quality and durability, suitable even for high optical powers.

AMS Technologies offers a broad selection of molded-glass aspheric optics from stock, in sizes ranging from 2.4 mm to 11.0 mm outer diameter with focal lengths from 8 mm to 22 mm. With design wavelengths from 405 nm to 9500 nm, these molded aspheric lenses aim at applications in the visible (VIS), near-infrared (NIR) and mid-infrared (MIR) wavebands, such as small beam collimation, focusing, and fiber coupling, with our precision molded infrared aspheric lenses being ideal for coupling of quantum cascade lasers (QCL).

Using Optics provides info on adjusting optics to fit yourself and caring for optics. Also basics of how binoculars and scopes work.

With this more sophisticated surface profile, an aspherical lens can reduce or eliminate both spherical and other aberrations, providing higher imaging quality such as a smaller focal point or a higher degree of collimation. Often, complex optical systems with multiple spherical lenses can be replaced by a single aspherical lens, resulting in less complexity, reduced dimensions, lower weight and often lower system costs.

Hands-on Review ~ They're the most comfortable binoculars I've ever held. They're really light. The barrels narrow in just the right place. They're not round in the center. They're designed for the way human hands are positioned when holding binoculars, with the narrowing on the diagonal. REVIEW | SEE IN STORE

DefinitionWhile the manufacturing and use of common spherical lenses (with both lens surfaces being part of surfaces of spheres, i.e. a spherical segment or spherical cap) are less complicated and expensive, the optical performance of spherical lenses is compromised by phenomena such as spherical aberration. So instead of a simple spherical lens, a more complex shaped lens is best suited for collimating and focusing tasks – an aspherical lens with at least one surface whose shape differs from a sphere. An aspheric lens surface typically is described by a radius of curvature and several parabolic or higher order terms.

Hands-on Review ~ It's stunning from the moment you meet it. We've never seen a binocular with a shape quite like the NL Pure. It seems it was made to fit your hand. It has the widest field of view of any top binocular. REVIEW | SEE IN STORE

The main focus knob adjusts both the left and the right sides of the binocular at the same time. However, your two eyes may not focus at exactly the same distance, so you would be left with one eye slightly out of focus. In case yours eyes have such a difference, the diopter adjustment lets you change the focus of just the right side. Here's how to set it.

Hands-on Review ~ In 2018, Kowa came out with a new 55mm Prominar travel scope. It is a remarkably small scope. It features the esteemed Kowa fluorite objective lens which has made the 88mm Kowa Prominar so popular. Here we compare the TSN-553 to four other travel scopes, including the economical Vortex Razor and the high-end Swarovski 65mm ATX.

More binoculars are ruined by bad cleaning technique than by being dropped. You've seen someone do it. Breathe on the binocular's eyepiece and then rub the glass with the corner of a shirt. Poor birder, he never knew he just degraded every image he would ever see with that binocular again. Here's the right way to clean your binoculars.
